[PATCH] drm: Remove some useless memset

From: Christophe JAILLET
Date: Thu Dec 09 2021 - 17:03:07 EST


'bufs' is an array embedded in an structure (struct drm_device_dma) which
is kzalloc just a few lines above.
So there is no need to explicitly memset each element on the array. It is
already cleared.

Remove the useless memset.
