Don't export format_by_forcc on two different drivers

2011-01-07T21:58:54+00:00

commit a757ee2216211278680dd8ac869aabe7b4a9970d upstream.

Drivers should append their name on exported symbols, to avoid
conflicts with allyesconfig:

drivers/staging/built-in.o: In function `format_by_fourcc':
/home/v4l/work_trees/linus/drivers/staging/cx25821/cx25821-video.c:96: multiple definition of `format_by_fourcc'
drivers/media/built-in.o:/home/v4l/work_trees/linus/drivers/media/common/saa7146_video.c:88: first defined here

Let's rename both occurences with a small shellscript:

for i in drivers/staging/cx25821/*.[ch]; do sed s,format_by_fourcc,cx25821_format_by_fourcc,g <$i >a && mv a $i; done
for i in drivers/media/common/saa7146*.[ch]; do sed s,format_by_fourcc,saa7146_format_by_fourcc,g <$i >a && mv a $i; done
for i in include/media/saa7146*.[ch]; do sed s,format_by_fourcc,saa7146_format_by_fourcc,g <$i >a && mv a $i; done

V4L/DVB: V4L: do not autoselect components on embedded systems

2010-08-09T02:43:02+00:00

Tuner, DVB frontend and video helper chip drivers are by default
autoselected by their respective host cards, this, however, doesn't make
much sense on SoC-based systems. Disable autoselection on EMBEDDED
systems.

V4L/DVB: xc5000, rework xc_write_reg

2010-08-02T18:29:10+00:00

Rework xc_write_reg function for correct read register of the xc5000.
It is very useful for tm6000.

Tested for tm6000 and for saa7134 works well.

V4L/DVB: videobuf: Remove the videobuf_sg_dma_map/unmap functions

2010-08-02T18:21:45+00:00

Instead of creating dirty wrappers around videobuf_dma_map/unmap that
create a dummy videobuf_queue structure, modify videobuf_dma_map/unmap
to take a device pointer argument and use it directly. The
videobuf_sg_dma_map/unmap then become unused and can be removed.

V4L/DVB: tda18271: fix error detection during initialization of first instance

2010-08-02T17:48:43+00:00

Fix error detection of failures during initialization of first instance:
Dont pass a function into the tda_fail macro. Instead, save the function
return value and pass that into the tda_fail macro.

This prevents the function from being called twice in cases of failure,
for example:

[19026.074070] tuner 4-0060: chip found @ 0xc0 (device #0)
[19026.087755] tda18271 4-0060: creating new instance

V4L/DVB: xc3028: fix regression in firmware loading time

2010-05-18T03:43:45+00:00

Fix a regression in the firmware loading time where it went from 1080 ms to
4700 ms.  This was noticed when the em28xx based HVR-950 took noticably longer
to load the driver.

Regression introduced in hg 12824.  The developer added an msleep() call with
an argument based on a newly introduced xc3028_ctrl field, which is left
initialized to zero for pretty much every board that is currently supported.
