[PATCH] drm/vmwgfx: remove DRM_ERROR message, stops log spamming

From: Colin King
Date: Tue Sep 12 2017 - 13:35:41 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

mmap'ing the device multiple times will spam the kernel log with the
DRM_ERROR message about illegal mmap'ing the old fifo space. Since
the mmap'ing will fail with an -EINVAL there is no need to emit this
message, so just remove it.
