[PATCH 0/6] drm/fsl-dcu: unload fixes
Hi all, This patchset fixes several issues around unloading/unbinding the driver. There is still one WARNING when unloading the driver while vblank interrupts are enabled. I am not sure what/who should make sure that vblank interrupts get disabled before unloading the driver: root@colibri-vf:~# echo 40058000.dcu > /sys/bus/platform/drivers/fsl-dcu/unbind [ 37.209656] Console: switching to colour dummy device 80x30 [ 37.224954] [ cut here ] [ 37.245375] WARNING: CPU: 0 PID: 170 at drivers/gpu/drm/drm_irq.c:380 drm_vblank_cleanup+0x5c/0x8c ...
