Subject: arch: imx: fix incorrect shutdown call for inactive video devices
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=670a20de08da8dd04b45c56ad69b440558cc99ee;p=thirdparty%2Fu-boot.git

arch: imx: fix incorrect shutdown call for inactive video devices

Somehow I missed that ipuv3_fb_shutdown() can be called for inactive
devices, resulting in invalid memory access and preventing the kernel
from booting.

Fixes: 32da6773f62 ("video: imx: ipuv3: refactor to use dm-managed state")
