Commit 7a6f6c29d2 (cx231xx: use
URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer
for URB twice. This works for the URBs allocated with usb_alloc_urb(),
as those are allocated from cohernent DMA pools, but the flag was also
added for the VBI and audio URBs, which have a manually allocated area.
This leaves the random trash in the structure after allocation as the
DMA address, corrupting memory and preventing VBI and audio from
working. Letting the USB core map the buffers solves the problem.

Most calls to cx231xx_capture_start() already use the values from
TRANSFER_TYPE, but cx231xx_capture_start() and
cx231xx_initialize_stream_xfer() were hand coding the values.
Use the named values (81 is never passed in), and simplify
cx231xx_capture_start(), as the switch statements were identical and
pcb_config->config_num is a u8, so any non-zero config got the same
result.

After this patch, the MEDIA*_SUPPORT will be used as a filter,
exposing only devices that are pertinent to one of the 3
V4L types: webcam/grabber, radio, analog TV.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
In the past, it was possible to have either DVB or V4L2 core
as module and the other as builtin. Such config never make much
sense, and created several issues in order to make the Kconfig
dependency to work, as all drivers that depend on both (most
TV drivers) would need to be compiled as 'm'. Due to that,
the VIDEO_MEDIA config option were added.
Instead of such weird approach, let's just use the MEDIA_SUPPORT
=y or =m to select if the media subsystem core will be either
builtin or module, simplifying the building system logic.
Also, fix the tuners configuration, by enabling them only if
a tuner is required. So, if just webcam/grabbers support is
selected, no tuner option will be selected. Also, if only digital
TV is selected, no analog tuner support is selected.
That removes the need of using EXPERT customise options, when
analog TV is not selected.

Change the main items to:
<m> Multimedia support --->
[ ] Cameras/video grabbers support
[ ] Analog TV support
[ ] Digital TV support
[ ] AM/FM radio receivers/transmitters support
[ ] Remote Controller support
This provides an interface that is clearer to end users that
are compiling the Kernel, and will allow the building system
to automatically unselect drivers for unused functions.

Change the firmware logic to use request_firmware_nowait(), and
to preserve the loaded firmwares in memory, to reduce the risk
of troubles with buggy userspace apps.
With this change, while the firmware is being loaded, the driver
will return -EAGAIN to any calls. If, for some reason, firmware
failed to be loaded from userspace, it will return -ENODEV.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
If firmware is not loaded for some reason, or if it is not ready
yet, it makes no sense to honour to any DVB callbacks.
So, return -EAGAIN, as the error condition may be temporary.
If the device doesn't initialize, either because it requires a
firmware or because there's an error during init_drxk, returns
-ENODEV, to indicate such error, on all DVB callbacks.

The firmware blob may not be available when the driver probes.
Instead of blocking the whole kernel use request_firmware_nowait() and
continue without firmware.
This shouldn't be that bad on drx-k devices, as they all seem to have an
internal firmware. So, only the firmware update will take a little longer
to happen.
