Subject: [PATCH] media: bcm2835-unicam: Retain packing information on
|
|
G_FMT
|
|
|
|
The change to retrieve the pixel format always on g_fmt didn't
|
|
check whether the native or unpacked version of the format
|
|
had been requested, and always returned the packed one.
|
|
Correct this so that the packing setting is retained whereever
|
|
possible.
|
|
|
|
Fixes "9d59e89 media: bcm2835-unicam: Re-fetch mbus code from subdev
|
|
on a g_fmt call"
