Subject: [PATCH] media: i2c: imx290: Group functions in sections
|
||
|
|
||
|
Upstream commit cb7e1c8dbe60
|
||
|
|
||
|
Move functions around to group them in logical sections, in order to
|
||
|
improve readability. As a result, the IMX290_NUM_SUPPLIES macro has to
|
||
|
be changed. No other code change is included, only moves.
