[PATCH v5] media: au0828 - convert to use videobuf2

From: Shuah Khan
Date: Fri Jan 23 2015 - 14:41:29 EST

Convert au0828 to use videobuf2. Tested with NTSC.
Tested video and vbi devices with xawtv, tvtime,
and vlc. Ran v4l2-compliance to ensure there are
no failures.

Video compliance test results summary:
Total: 75, Succeeded: 75, Failed: 0, Warnings: 18

Vbi compliance test results summary:
Total: 75, Succeeded: 75, Failed: 0, Warnings: 0

Signed-off-by: Shuah Khan <shuahkh@xxxxxxxxxxxxxxx>
---
Changes since patch v4:
- Updated commit log with correct compliance test
results.
Changes since patch v3:
- Removed unnecessary ret = 0 in au0828_v4l2_open()
- Rest of the patches in the v3 series are good.
No need to resend them.
