Subject: video: fbdev-MMP: Remove call to memset after dma_alloc_coherent
Git-commit: 8cbff03bb090d537063c935058ab6fceb8ee30f5
Patch-mainline: v5.4-rc1
References: bsc#1152472

In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
