V4L/DVB: pxa_camera: move fifo reset direct before dma start

2010-05-06T22:20:52+00:00

Move the fifo reset from pxa_camera_start_capture to pxa_camera_irq direct
before the dma start after an end of frame interrupt to prevent images from
shifting because of old data at the begin of the frame.

V4L/DVB: video: testing unsigned for less than 0

2010-05-06T22:20:52+00:00

soc_mbus_bytes_per_line() returns -EINVAL on error but we store it in an
unsigned int so the test for less than zero doesn't work.  I think it
always returns "small" positive values so we can just cast it to int
here.

V4L/DVB: budget: Oops: "BUG: unable to handle kernel NULL pointer dereference"

2010-05-06T22:20:51+00:00

Never call dvb_frontend_detach if we failed to attach a frontend. This fixes
the following oops, which will be triggered by a missing stv090x module:

V4L/DVB: saa7146: fix regression of the av7110/budget-av driver

2010-05-06T22:20:50+00:00

An earlier regression fix for the mxb driver (V4L/DVB: saa7146_vv: fix
regression where v4l2_device was registered too late) caused a new
regression in the av7110 driver.

Reverted the old fix and fixed the problem in the mxb driver instead.
Tested on mxb and budget-av cards.

The real problem is that the saa7146 framework has separate probe()
and attach() driver callbacks which should be rolled into one. This
is now done for the mxb driver, but others should do the same. Lack
of hardware makes this hard to do, though. I hope to get hold of some
hexium cards and then I can try to improve the framework to prevent
this from happening again.

V4L/DVB: V4L - vpfe capture - fix for kernel crash

2010-05-06T22:19:05+00:00

As part of upstream merge, set_params() function was removed from isif.c.
This requires removal of BUG_ON() and check for set_params ptr in
vpfe_capture.c. Without this kernel crash dump is seen while bootup on DM365

Also made following changes:-

 1) converted error messages to debug messages since it is not right to flood
    the console with error messages for user mistakes.
 2) returns -EINVAL if ioctl is not supported

2010-05-06T22:19:04+00:00

The 046d:08da usb id shouldn't be associated with the stv06xx driver as they're
not compatible with each other.
This fixes a bug where Quickcam Messenger cams fail to use its proper driver
(gspca-zc3xx), rendering the camera inoperable.
