[RFC PATCH 0/2] davinci: convert to core-assisted locking

[RFC PATCH 0/2] davinci: convert to core-assisted locking

[Hans Verkuil]

These two patches convert vpif_capture and vpif_display to core-assisted
locking and now use .unlocked_ioctl instead of .ioctl.

These patches assume that the 'DaVinci VPIF: Support for DV preset and DV
timings' patch series was applied first. See:

http://www.mail-archive.com/linux-media@vger.kernel.org/msg26594.html

These patches are targeted for 2.6.38.

Regards,

	Hans

[RFC PATCH 1/2] davinci: convert vpif_capture to core-assisted locking

[Hans Verkuil]

From: Hans Verkuil <hans.verkuil@cisco.com>

Now uses .unlocked_ioctl instead of .ioctl.

Shall I add these two patches as well to the pull request I sent
yesterday[1]? These changes are localized to the DaVinci VPIF driver
and should be safe to take in.

I can also send a separate pull request.

Let me know and I will do that way.

Thanks,
Sekhar
