+Subject: [PATCH] media: i2c: imx290: Explicitly set v&h blank on
+ mode change
+
+__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.
