ivtv: Fix PCI DMA direction

2009-06-05T15:05:23+00:00

The ivtv stream buffers may be for receive or for send but the attached
sg handle is always destined cpu->device.  We flush it correctly but the
allocation is wrongly done with the same type as the buffers.

See bug: http://bugzilla.kernel.org/show_bug.cgi?id=13385

(Note this doesn't close the bug - it fixes the ivtv part and in turn
the logging next shows up some rather alarming DMA sg list warnings in
libata)

2009-05-09T21:53:16+00:00

V4L2_TUNER_MODE_ was used in a few places where V4L2_TUNER_SUB_ should have
been used.

V4L/DVB (11669): uvc: fix compile warning

2009-05-09T21:52:40+00:00

The 2.6.30 kernel generates this warning:

uvc_driver.c:1729: warning: 'ret' may be used uninitialized in this function

I guess some new warning flag must have been turned on since this warning
didn't appear with older kernels (gcc version 4.3.1). It's also a bogus
warning, but since this code didn't comply to the coding standard anyway
I've modified it to 1) remove the warning and 2) conform to the coding
standard.

The boards control struct wasn't updated when (presumably) all of the

V4L/DVB (11662): v4l2-ioctl: Clear buffer type specific trailing fields/padding

2009-05-09T21:51:48+00:00

Some ioctls have structs that are a different size depending on what type
of buffer is being used.  If the buffer type leaves a field unused or has
padding space at the end, this space should be zeroed out.

The problems with S_FMT and REQBUFS were original identified and patched by
Marton Nemeth .

V4L/DVB (11661): v4l2-ioctl: Check buffer types using g_fmt instead of try_fmt

2009-05-09T21:51:18+00:00

For a number of different ioctls, the v4l2-ioctl code checks that the
passed buffer type is supported by the driver.  It did this by checking
that the driver defined a method for the try_fmt handler for that buffer
type.  However, try_fmt is optional and a driver might not provide it even
though it does support that type.  So use g_fmt instead, since that isn't
optional.

This should fix a problem with VBI capture with saa7146.
