V4L/DVB (5123): Buf_qbuf: fix: videobuf_queue->stream corruption and lockup

2007-01-24T00:00:21+00:00

We are doing ->buf_prepare(buf) before adding buf to q->stream list. This
means that videobuf_qbuf() should not try to re-add a STATE_PREPARED buffer.

V4L/DVB (5023): Fix compilation on ppc32 architecture

2007-01-15T18:33:51+00:00

There's a problem, pointed by Meelis Roos , that, on ppc32 arch,
with some gcc versions (noticed with prerelease 4.1.2 20061115), compilation 
fails, due the lack of __ucmpdi2 to do the required 64-bit comparision.
This patch takes some sugestions made by Andrew Morton ,
Stelian Pop  and Segher Boessenkool

buffers.

V4L/DVB (5024): Fix quickcam communicator driver for big endian architectures

2007-01-15T18:25:48+00:00

Host endianess does not affect the order that pixel rgb data comes
in from the quickcam (the values are bytes, not words or longs).  The
driver is erroniously swapping the order of rgb values for big endian
machines.  This patch is needed get the Quickcam communicator working
on big endian machines (tested on powerpc)

V4L/DVB (5021): Cx88xx: Fix lockup on suspend

2007-01-15T18:25:31+00:00

Suspending with the cx88xx module loaded causes the system to lock up
because the cx88_audio_thread kthread was missing a try_to_freeze()
call, which caused it to go into a tight loop and result in softlockup
when suspending. Fix that.

V4L/DVB (5020): Fix: disable interrupts while at KM_BOUNCE_READ

2007-01-15T18:25:28+00:00

vivi.c uses the KM_BOUNCE_READ with local interrupts enabled. 
This means that if a disk interrupt occurs while vivi.c is using this
fixmap slot, the vivi.c driver will, upon return from that interrupt, find
that the fixmap slot now points at a different physical page.
The net result will probably be rare corruption of disk file contents,
because viv.c will now be altering the page which the disk code was
recently using. 

Thanks to Andrew Morton for pointing this.

V4L/DVB (5019): Fix the frame->grabstate update in read() entry point.

2007-01-15T18:25:24+00:00

The Coverity checker spotted that in usbvision_v4l2_read(), the variable
"frmx" is never assigned any value different from -1, but it's used an 
an array index in "usbvision->frame[frmx]".
Thanks to Adrian Bunk  for warning about that.
