Re: [PATCH 1/3] drm: Remove DRM_ARRAY_SIZE() for ARRAY_SIZE()

On Mon, Jun 9, 2014 at 9:39 AM, Damien Lespiau damien.lespiau@intel.com wrote:

I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used in a few places. I suspect its usage has been spread by copy & paste rather than anything else.

Let's just remove it for plain ARRAY_SIZE().
