Subject: [PATCH] media: i2c: imx477: Remove internal
|
||
|
|
v4l2_mbus_framefmt from the state
|
||
|
|
|
||
|
|
The only field in this struct that is used is the format code, so
|
||
|
|
replace the struct with this single field.
|
||
|
|
|
||
|
|
Save the format code in imx477_set_pad_format() when setting up a new
|
||
|
|
mode so that imx477_get_pad_format() performs the right lookup.
|
||
|
|
Otherwise, this caused a bug where the mode lookup occurred on the
|
||
|
|
12-bit table rather than the 10-bit table.
|
||
