Greg Kroah-Hartman 86281966c7 Second set of fixes for IIO in the 3.15 cycle.
* ad2s1200 - Fix some missing parenthesis in a for statement that could have
   led to an error being missed when getting gpios.
 * Fix a null derefference issue in the mpu6050 when platform data is not
   provided (or is provided via the device tree for example).
 * exynos_adc bug on remove due to child devices having been added to the
   parent of the IIO device rather than the IIO device itself.  This caused an
   issue with the IIO device removing itself in it's remove function.
 * Make all ADC drivers buildable as modules to avoid dependency issues if
   the IIO core is itself built as a module.  The exynos adc bug became
   apparently whilst this fix was being tested.

Shawn Guo a3fe964135 imx-drm: imx-tve: correct DDC property name to 'ddc-i2c-bus'
Commit 62e3879 (imx-drm: imx-tve: Fix DDC I2C bus property) was trying
to use 'ddc-i2c-bus' as the DDC property name (we can see that from the
commit log), but unfortunately 'i2c-ddc-bus' which is a typo was
actually used in the code.  This results in some unnecessary
inconsistency and confusions, because all the documented DDC property
in device tree bindings use 'ddc-i2c-bus'.

  Documentation/devicetree/bindings/staging/imx-drm/hdmi.txt
  Documentation/devicetree/bindings/panel/simple-panel.txt
  Documentation/devicetree/bindings/video/dvi-connector.txt

Let's fix it before the error spreads.

H Hartley Sweeten 2704f807f9 staging: comedi: usbdux: bug fix for accessing 'ao_chanlist' in private data
In usbdux_ao_cmd(), the channels for the command are transfered from the
cmd->chanlist and stored in the private data 'ao_chanlist'. The channel
numbers are bit-shifted when stored so that they become the "command"
that is transfered to the device. The channel to command conversion
results in the 'ao_chanlist' having these values for the channels:

  channel 0 -> ao_chanlist = 0x00
  channel 1 -> ao_chanlist = 0x40
  channel 2 -> ao_chanlist = 0x80
  channel 3 -> ao_chanlist = 0xc0

The problem is, the usbduxsub_ao_isoc_irq() function uses the 'chan' value
from 'ao_chanlist' to access the 'ao_readback' array in the private data.
So instead of accessing the array as 0, 1, 2, 3, it accesses it as 0x00,
0x40, 0x80, 0xc0.

Fix this by storing the raw channel number in 'ao_chanlist' and doing the
bit-shift when creating the command.

Shawn Guo 1c2366298b imx-drm: imx-drm-core: skip components whose parent device is disabled
In a board setup which disables LDB device node completely by changing
status to 'disabled', and only enables HDMI device, we're running into
the problem that imx-drm master never succeeds in binding, and hence
HDMI does not come up either.

&ldb {
	status = "disabled";

	lvds-channel@1 {
		...
		status = "okay";
	};
};

The imx-drm-core should really skip the LVDS channels no matter what
lvds-channel's status is, if LDB device is disabled.  Let's consider
such setup a misconfiguration, give a warning in there and not add the
component.

Tomi Valkeinen f7018c2135 video: move fbdev to drivers/video/fbdev
The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

                               lock(&mm->mmap_sem);
  lock(&dev->mutex#2);

 *** DEADLOCK ***

To avoid the circular dependency, just try to get the lock in
`comedi_mmap()` instead of blocking.  Since the comedi device's main mutex
is heavily used, do a down-read of its `attach_lock` rwsemaphore
instead.  Trying to down-read `attach_lock` should only fail if
some task has down-write locked it, and that is only done while the
comedi device is being attached to or detached from a low-level hardware
device.

Unfortunately, acquiring the `attach_lock` doesn't prevent another
task replacing the comedi data buffer we are trying to mmap.  The
details of the buffer are held in a `struct comedi_buf_map` and pointed
to by `s->async->buf_map` where `s` is the comedi subdevice whose buffer
we are trying to map.  The `struct comedi_buf_map` is already reference
counted with a `struct kref`, so we can stop it being freed prematurely.

Modify `comedi_mmap()` to call new function
`comedi_buf_map_from_subdev_get()` to read the subdevice's current
buffer map pointer and increment its reference instead of accessing
`async->buf_map` directly.  Call `comedi_buf_map_put()` to decrement the
reference once the buffer map structure has been dealt with.  (Note that
`comedi_buf_map_put()` does nothing if passed a NULL pointer.)

`comedi_buf_map_from_subdev_get()` checks the subdevice's buffer map
pointer has been set and the buffer map has been initialized enough for
`comedi_mmap()` to deal with it (specifically, check the `n_pages`
member has been set to a non-zero value).  If all is well, the buffer
map's reference is incremented and a pointer to it is returned.  The
comedi subdevice's spin-lock is used to protect the checks.  Also use
the spin-lock in `__comedi_buf_alloc()` and `__comedi_buf_free()` to
protect changes to the subdevice's buffer map structure pointer and the
buffer map structure's `n_pages` member.  (This checking of `n_pages` is
a bit clunky and I [Ian Abbott] plan to deal with it in the future.)

A string of goto_buf has a number followed by x or y.

Jean Delvare 877ed14306 [media] Prefer gspca_sonixb over sn9c102 for all devices
The sn9c102 driver is deprecated. It was moved to staging in
anticipation of its removal in a future kernel version. However, USB
devices 0C45:6024 and 0C45:6025 are still handled by sn9c102 when
both sn9c102 and gspca_sonixb are enabled.

We must migrate all the users of these devices to the gspca_sonixb
driver now, so that it gets sufficient testing before the sn9c102
driver is finally phased out.

   From Florian Westphal.

 4) If VLAN untagging fails, we double free the SKB in the bridging
    output path.  From Toshiaki Makita.

 5) Several call sites of sk->sk_data_ready() were referencing an SKB
    just added to the socket receive queue in order to calculate the
    second argument via skb->len.  This is dangerous because the moment
    the skb is added to the receive queue it can be consumed in another
    context and freed up.

    It turns out also that none of the sk->sk_data_ready()
    implementations even care about this second argument.

    So just kill it off and thus fix all these use-after-free bugs as a
    side effect.

 6) Fix inverted test in tcp_v6_send_response(), from Lorenzo Colitti.

 7) pktgen needs to do locking properly for LLTX devices, from Daniel
    Borkmann.

 8) xen-netfront driver initializes TX array entries in RX loop :-) From

David S. Miller 676d23690f net: Fix use after free by removing length arg from sk_data_ready callbacks.
Several spots in the kernel perform a sequence like:

	skb_queue_tail(&sk->s_receive_queue, skb);
	sk->sk_data_ready(sk, skb->len);

But at the moment we place the SKB onto the socket receive queue it
can be consumed and freed up.  So this skb->len access is potentially
to freed up memory.

Furthermore, the skb->len can be modified by the consumer so it is
possible that the value isn't accurate.

And finally, no actual implementation of this callback actually uses
the length argument.  And since nobody actually cared about it's
value, lots of call sites pass arbitrary values in such as '0' and
even '1'.

So just remove the length argument from the callback, that way there
is no confusion whatsoever and all of these use-after-free cases get
fixed as a side effect.

Based upon a patch by Eric Dumazet and his suggestion to audit this
issue tree-wide.

Jes Sorensen dda26427bd staging: rtl8723au: The 8723 only has two paths
Converting the driver from the original RTL provided version, by error
converted the code to use four, which caused all sorts of issues. The
confusion was caused by the RTL driver having support for both two and
four paths, and in some places had RF_PATH_MAX = 3. At the same time
it kept the data structures hard coded for two paths, in particular
the ones matching the efuse data.

Greg Kroah-Hartman 806192c07d Staging: unisys: mark drivers as BROKEN
Turns out these drivers like to mess around with the system even if the
hardware they control isn't present.  That's not good, and people are
starting to report lots of issues with this in their build/boot testing.

So for now, let's just mark them as BROKEN, until the code gets
converted to use the proper driver model interaction (i.e. don't do
anything until the hardware is actually found in the system.)

Larry Finger f004e55947 staging: r8723au: Fix build problem when RFKILL is not selected
The kbuild test robot reports the following build errors for x86_64-randconfig-c1-0407:

All error/warnings:

   net/built-in.o: In function `nl80211_start_p2p_device':

These undefined sysbols are all satisfied if a "select RFKILL" is added to
Kconfig. This "fix" leads to another problem as follows:

>> nl80211.c:(.text+0x9032e): undefined reference to `rfkill_blocked'
net/rfkill/Kconfig:4:error: recursive dependency detected!
net/rfkill/Kconfig:4:   symbol RFKILL is selected by R8723AU
drivers/staging/rtl8723au/Kconfig:1:    symbol R8723AU depends on USB
drivers/usb/Kconfig:41: symbol USB is selected by MOUSE_APPLETOUCH
drivers/input/mouse/Kconfig:162:        symbol MOUSE_APPLETOUCH depends on INPUT
drivers/input/Kconfig:8:        symbol INPUT is selected by ACPI_CMPC
drivers/platform/x86/Kconfig:635:       symbol ACPI_CMPC depends on RFKILL

To avoid substituting one build error for another, I added a "depends on RFKILL".
My suspicion is that this particular error is caused by a kbuild bug, or that the
selection of INPUT by ACPI_CMPC is wrong. In any case, that will be solved separately.

Potentially overflowing expression "(f_rf + f_if + f_if1) * lo_div"
with type "unsigned int" (32 bits, unsigned) is evaluated using 32-bit
arithmetic before being used in a context which expects an expression
of type "u64" (64 bits, unsigned). To avoid overflow, cast either
operand to "u64" before performing the multiplication.
