[PATCH] video: fbdev: s3c-fb: remove redundant initialization of pointer bufs

From: Colin Ian King
Date: Thu Dec 30 2021 - 11:06:33 EST


Pointer bufs is being initialized with a value that is never read, it
is being re-assigned with a different value later on. The assignment
is redundant and can be removed. Cleans up clang-scan warning:

drivers/video/fbdev/s3c-fb.c:492:16: warning: Value stored to 'buf'
during its initialization is never read [deadcode.DeadStores]
void __iomem *buf = regs;
