Subject: drm: Prefer kmalloc_array() over kmalloc() with multiply
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=2f6c538924108fbffb72a0696f28537b364080fa;p=linux-beck.git

drm: Prefer kmalloc_array() over kmalloc() with multiply

Fixes a couple of checkpatch warnings regarding the use of kmalloc()
with a multiplication. kmalloc_array() is the preferred API.
