Subject: [PATCH] media: bcm2835-unicam: Re-fetch mbus code from subdev
|
|
on a g_fmt call
|
|
|
|
The sensor subdevice may change the Bayer order if a H/V flip is
|
|
requested after a s_fmt call. Unicam g_fmt must call the subdev get_fmt
|
|
in case this has happened and return out the correct format 4cc.
