tuner_xc2028: Allow selection of the frequency adjustment code for XC3028

2011-11-11T17:43:28+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

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

2011-11-11T17:43:27+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.

[media] videodev: fix a NULL pointer dereference in v4l2_device_release()

2011-10-19T11:48:08+00:00

The change in 8280b66 does not cover the case when v4l2_dev is already
NULL, fix that.

With a Kinect sensor, seen as an USB camera using GSPCA in this context,
a NULL pointer dereference BUG can be triggered by just unplugging the
device after the camera driver has been loaded.

[media] uvcvideo: Fix crash when linking entities

2011-09-22T01:18:07+00:00

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.

[media] v4l: Make sure we hold a reference to the v4l2_device before using it

2011-09-22T01:17:53+00:00

v4l2_device_disconnect() calls dev_get_drvdata() and dev_set_drvdata()
on the device it received in v4l2_device_register(). Get a reference to
the device in v4l2_device_register() to make sure it won't disappear as
long as we need it.

[media] v4l: Fix use-after-free case in v4l2_device_release

2011-09-22T01:17:43+00:00

Drivers that have no v4l2_device release callback might free the
v4l2_device instance in the video_device release callback. Make sure we
don't access the v4l2_device instance after it gets freed.

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

2011-09-22T01:17:14+00:00

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.

[media] OMAP_VOUT: Fix build break caused by update_mode removal in DSS2

2011-09-22T01:16:08+00:00

The DSS2 driver does not support the configuration of the update_mode of a
panel anymore. Remove the setting of update_mode done in omap_vout_probe().
Ignore configuration of TE since omap_vout driver doesn't support manual update
displays anyway.
