[media] mt9v022: set y_skip_top field to zero as default

Set "y_skip_top" to zero and revise comment as I do not see this line
corruption on two different mt9v022 setups. The first read-out line
is perfectly fine. Add mt9v022 platform data configuring y_skip_top
for platforms that have issues with the first read-out line. Set
y_skip_top to 1 for pcm990 board.

[media] v4l: Don't warn during link validation when encountering a V4L2 devnode

v4l2_subdev_link_validate_get_format() retrieves the remote pad format
depending on the entity type and prints a warning if the entity type is
not supported. The type check doesn't take the subtype into account, and
thus always prints a warning for device node types, even when supported.
Fix it.

[media] davinci: vpif_capture: fix return type check for v4l2_subdev_call()

The v4l2_subdev_call() call returns -ENODEV when subdev is
null and -ENOIOCTLCMD wnen no icotl is present.
This patch fixes the return type check for v4l2_subdev_call().
The pattern E == C1 && E == C2 is always false. This patch
fix this according to the assumption that && should be ||.

In case of error, the function vb2_dma_contig_init_ctx() returns
ERR_PTR() and never returns NULL. The NULL test in the return value
check should be replaced with IS_ERR().

ALSA: hda - Don't overwrite the pin default configs

Since we keep the pin default config values anyway internally, we
don't have to set the values in the codec.  This patch removes the
code writing the pincfg values.

As a gratis bonus, we can remove also the code restoring the original
pincfg values at PM resume or module free.  This will give us more
benefit, as it can reduce the unnecessary power-up of codecs.

This won't change the driver functionality.  The only difference would
be that the codec proc file will show the original pincfg values
instead of the actually referred values.  The actually referred values
can be determined from sysfs *_pin_configs files.
(Also hda-emu was updated to follow this change.)

ALSA: hda - Don't release firmware when CONFIG_PM is set

The new firmware code tries to re-read the formerly read firmware
files before suspend.  Thus it's wiser to keep the "patch" firmware in
the driver for avoiding this unnecessary re-reading.

Of course, this will consume a bit of memory for unused stuff, but
the patch fw is supposed to be fairly small, so it's more benefit in
the end.
