We should not change gadget driver's descriptors just
because we think it's right to do so.
There are several of reasons which would support this
statement but it suffices to say that this was probably
never tested because it updates bmAttributes without
asking the driver if it's ok to do so.
This means that e.g. on UASP gadget it would enable
stream support even for the command endpoint which must
not have stream support enabled.
In fact, this change is fixing the bug introduced by
commit a59d6b9 (usb: gadget: add streams support to
the gadget framework) which was caught when testing
UASP gadget with dwc3 driver.

When the last RFCOMM data channel is closed, a timer is normally set
up to disconnect the control channel at a later time. If the control
channel disconnect command is sent with the timer pending, the timer
needs to be cancelled.
If the timer is not cancelled in this situation, the reference
counting logic for the RFCOMM session does not work correctly when the
remote device closes the L2CAP connection. The session is freed at
the wrong time, leading to a kernel panic.

I noticed that hotplug of one setup does not work with recent change in
pci tree.
After checking the bridge conf setup, I noticed that the bridges get
assigned but do not get enabled.
The reason is the following commit, while simply ignores bridge
resources when enabling a pci device:
| commit bbef98ab0f
| Author: Ram Pai <linuxram@us.ibm.com>
| Date: Sun Nov 6 10:33:10 2011 +0800
|
| PCI: defer enablement of SRIOV BARS
|...
| NOTE: Note, there is subtle change in the pci_enable_device() API. Any
| driver that depends on SRIOV BARS to be enabled in pci_enable_device()
| can fail.
Put back bridge resource and ROM resource checking to fix the problem.
That should fix regression like BIOS does not assign correct resource to
bridge.

Commit 5c48b108 ("um: take arch/um/sys-x86 to arch/x86/um") broke the
make target update-po-config, as its symlink trick (again) fails.
(Previous breakage was fixed with commit bdc69ca4 ("kconfig: change
update-po-config to reflect new layout of arch/um").)
The new UML layout allows to drop the symlick trick entirely. And if,
one day, another architecture supports UML too, that should now work
without again breaking this make target.

s3c24xx_i2c_parse_dt_gpio is called when cfg_gpio is not defined
in the platform data of the i2c device. When DT is not enabled,
the above function always returns -EINVAL. Since there can be
some i2c devices which don't need to configure any gpio lines,
the probe of such devices would fail here. Changing the default
return value to success would fix this issue.

For now, as semaphores interaction with VTd causes random issues on

via the semaphores=1 kernel parameter.
