From 39366dc393052244557e03bc60b0c699a7215b44 Mon Sep 17 00:00:00 2001 From: Dave Stevenson Date: Tue, 7 Jul 2020 10:31:53 +0100 Subject: [PATCH 280/634] 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.
