Subject: [PATCH 269/828] media: i2c: imx290: Explicitly set v&h blank on mode

|
__v4l2_ctrl_modify_range only updates the current value should
|
|
|
|
|
it be invalid within the new range. That can leave modes producing
|
|
|
|
|
odd frame rates.
|
|
|
|
|
|
|
|
|
|
Explicitly update the HBLANK and VBLANK values so that on mode
|
|
|
|
|
change we revert to the default frame rate for the mode.
