Subject: drm/mgag200: Set cursor scanout address to correct BO
Git-commit: cf578c8c8e0b1fcd7c7de649effaf2c7625433c5
Patch-mainline: v5.4-rc1
References: bsc#1152472
The hardware requires the correct memory address of the buffer. Currently
the same BO's address is programmed unconditionally, so only every second
cursor update actually becomes visible.
