Subject: [PATCH] drm: change drm_err return type to void

The return value is not used by callers of this function
nor by uses of the DRM_ERROR macro so change the function
to return void.

Signed-off-by: Joe Perches <joe@...ches.com>
---
This change is associated to a desire to eventually
change printk to return void.

No x86 change in output size for drm_drv.o
