Commit Message

André Almeida April 26, 2019, 1:22 a.m. UTC
This commit adapts vimc-sensor to handle multiplanar pixel formats,
adapting the memory allocation and TPG configuration.

Signed-off-by: André Almeida <andrealmeid@collabora.com>
---
Changes in v4:
- Correct `unsigned int ret` to `int ret`
- Remove label `free_planes` from else scope

Changes in v3:
- Adapt to new vimc_frame

Changes in v2:
- Fix alignment issues
- Remove unnecessary variable assignment
- Reuse and share the code to free the memory of planes with a goto
