[media] sms: Remove CONFIG_ prefix from Kconfig symbols

X-Patchwork-Delegate: mchehab@redhat.com
Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for
SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files.

Note that the current (common sense) dependency on SMS_USB_DRV and
SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not
violate its constraints. These constraint are that:
- it should only be built if SMS_USB_DRV is set;
- it can't be builtin if USB support is modular.

So drop the dependency on SMS_USB_DRV, as it is unneeded.

[media] v4l2-ioctl: don't set PRIV_MAGIC unconditionally in g_fmt()

Regression fix:

V4L2_PIX_FMT_PRIV_MAGIC should only be set for the VIDEO_CAPTURE and
VIDEO_OUTPUT buffer types, and not for any others. In the case of
the win format this overwrote a pointer value that is passed in from
userspace.

Just set it for V4L2_BUF_TYPE_VIDEO_CAPTURE and OUTPUT only. Set
it before the callback is called, just as is done for try/s_fmt, and
again afterwards in case the driver zeroed it. The latter was missing
in try/s_fmt, so add it there as well. Currently it is quite likely
that drivers clear priv (that was needed for a long time), so it makes
sense to set it twice.

The fact that the pixelformat is using a packed RGB format has nothing
to do with the colorspace that is being used. Those are very different
things. The colorspace decides what color a triplet of RGB numbers
actually map to. E.g. a red color with values (255, 0, 0) is a different

e.g. YUV in colorspace REC709, then after the conversion to RGB the
colorspace is still REC709. Unless the hardware actually converted the
colorspace as well from REC709 to sRGB, but that rarely if ever happens.

Hans Verkuil [Thu, 17 Jul 2014 09:53:08 +0000 (06:53 -0300)]
[media] vb2: fix bytesused == 0 handling

The original report from Nikhil was that if data_offset > 0 and bytesused == 0,
then the check in __verify_length() would fail, even though the spec says that
if bytes_used == 0, then it will be replaced by the actual length of the
buffer.

After digging into it a bit more I realized that there were several other
things wrong:

- in __verify_length() it would use the application-provided length value
  for USERPTR and the vb2 core length for other memory models, but it
  should have used the application-provided length as well for DMABUF.

- in __fill_vb2_buffer() on the other hand it would replace bytesused == 0
  by the application-provided length, even for MMAP buffers where the
  length is determined by the vb2 core.

- in __fill_vb2_buffer() it tries to figure out if all the planes have
  bytesused == 0 before it will decide to replace bytesused by length.
  However, the spec makes no such provision, and it makes for convoluted
  code. So just replace any bytesused == 0 by the proper length.
  The idea behind this was that you could use bytesused to signal empty
  planes, something that is currently not supported. But that is better
  done in the future by using one of the reserved fields in strucy v4l2_plane.

This patch fixes all these issues.

Hans

[media] s5p: fix error code path when failing to allocate DMA memory

In the s5p_mfc_alloc_firmware() function there are some mistakes
where the code checks whether the DMA memory is properly allocated or
not.

First of all dma_alloc_coherent() returns NULL in case of error.
The code also checked two times fw_virt_addr, ignoring
the bank2_virt pointer.
