Subject: [PATCH] media: i2c: imx290: Factor out control update code to
|
||
|
|
a function
|
||
|
|
|
||
|
|
Upstream commit a7941da37c43
|
||
|
|
|
||
|
|
Move the control update code to a separate function to group it with all
|
||
|
|
the control-related code and make imx290_set_fmt() more readable.
