Subject: drm/mgag200: Pin displayed cursor BO to video memory
Git-commit: a0fd72d2c95b56c78feec0867f2077b5ff5991e6
Patch-mainline: v5.4-rc1
References: bsc#1152472
The cursor BO has to be pinned to video ram while it's being displayed.
With the current code, the BO might be pinned to system memory instead.
The patch fixes this problem.
