Subject: [PATCH] media: i2c: imx290: Use device lock for the control
|
||
|
|
handler
|
||
|
|
|
||
|
|
Upstream commit 08878cbc0cbf.
|
||
|
|
|
||
|
|
The link frequency and pixel rate controls are set without holding the
|
||
|
|
control handler lock, resulting in kernel warnings. As the value of
|
||
|
|
those controls depend on the format, the simplest fix is to use the
|
||
|
|
device lock for the control handler.
