   4 Subject: [PATCH] media: i2c: imx290: Use device lock for the control
   5  handler
   6
   7 Upstream commit 08878cbc0cbf.
   8
   9 The link frequency and pixel rate controls are set without holding the
  10 control handler lock, resulting in kernel warnings. As the value of
  11 those controls depend on the format, the simplest fix is to use the
  12 device lock for the control handler.
