media: s5p-fimc: Use correct fourcc for RGB565 colour format

2012-01-06T22:13:54+00:00

commit f83f71fda27650ae43558633be93652577dbc38c upstream.

With 16-bit RGB565 colour format pixels are stored by the device in memory
in the following order:

    | b3  | b2  | b1  | b0  |
   ~+-----+-----+-----+-----+
    | R5 G6 B5  | R5 G6 B5  |

This corresponds to V4L2_PIX_FMT_RGB565 fourcc, not V4L2_PIX_FMT_RGB565X.
This change is required to avoid trouble when setting up video pipeline
with the s5p-tv devices, so the colour formats at both devices can be
properly matched.

saa7164: Add support for another HVR2200 hardware revision

2011-11-26T17:09:53+00:00

commit 62dd28d0c659db29bdb89cfe9f0aefe42f0adfe9 upstream.

Hauppauge have released a new model rev, sub id 8940, this adds
support.

 card numbering in saa7164.h, appending rather than inserting the new card

tuner_xc2028: Allow selection of the frequency adjustment code for XC3028

2011-11-11T17:36:14+00:00

commit 9bed77ee2fb46b74782d0d9d14b92e9d07f3df6e upstream.

This device is not using the proper demod IF. Instead of using the
IF macro, it is specifying a IF frequency. This doesn't work, as xc3028
needs to load an specific SCODE for the tuner. In this case, there's
no IF table for 5 MHz.

dib0700: protect the dib0700 buffer access

2011-11-11T17:36:14+00:00

commit bff469f4167fdabfe15294f375577d7eadbaa1bb upstream.

This patch protects the common buffer access inside the dib0700 in order
to manage concurrent access. This protection is done using mutex.

DiBcom: protect the I2C bufer access

2011-11-11T17:36:14+00:00

commit 79fcce3230b140f7675f8529ee53fe2f9644f902 upstream.

This patch protects the I2C buffer access in order to manage concurrent
access. This protection is done using mutex.
Furthermore, for the dib9000, if a pid filtering command is
received during the tuning, this pid filtering command is delayed to
avoid any concurrent access issue.

uvcvideo: Set alternate setting 0 on resume if the bus has been reset

2011-11-11T17:36:13+00:00

commit d59a7b1dbce8b972ec2dc9fcaaae0bfa23687423 upstream.

If the bus has been reset on resume, set the alternate setting to 0.
This should be the default value, but some devices crash or otherwise
misbehave if they don't receive a SET_INTERFACE request before any other
video control request.

Microdia's 0c45:6437 camera has been found to require this change or it
will stop sending video data after resume.

uvcvideo: Fix crash when linking entities

2011-10-25T05:10:15+00:00

commit 4d9b2ebd335d83044b9e6656d0e604e8e1300334 upstream.

The uvc_mc_register_entity() function wrongfully selects the
media_entity associated with a UVC entity when creating links. This
results in access to uninitialized media_entity structures and can hit a
BUG_ON statement in media_entity_create_link(). Fix it.

vp7045: fix buffer setup

2011-10-03T18:40:16+00:00

commit fc61ccd35fd59d5362d37c8bf9c0526c85086c84 upstream.

dvb_usb_device_init calls the frontend_attach method of this driver which
uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to
be allocated before that happens.

Luckily we can use the whole private data as the buffer as it gets separately
allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for
use via usb_control_msg.

This fixes a
	BUG: unable to handle kernel paging request at 0000000000001e78

nuvoton-cir: simplify raw IR sample handling

2011-10-03T18:40:15+00:00

commit de4ed0c111ed078b8729a5cc49c23197740f5bad upstream.

The nuvoton-cir driver was storing up consecutive pulse-pulse and
space-space samples internally, for no good reason, since
ir_raw_event_store_with_filter() already merges back to back like
samples types for us. This should also fix a regression introduced late
in 3.0 that related to a timeout change, which actually becomes correct
when coupled with this change. Tested with RC6 and RC5 on my own
nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky
behavior in 3.0 due to the timeout change.
