Subject: [PATCH 3/5] drm/i915: Remove unused ring argument from frontbuffer invalidate and busy functions.
Date: Thu, 18 Jun 2015 11:43:24 -0700	[thread overview]
Message-ID: <1434653006-5693-3-git-send-email-rodrigo.vivi@intel.com> (raw)
In-Reply-To: <1434653006-5693-1-git-send-email-rodrigo.vivi@intel.com>

This patch doesn't have any functional change, but organize fruntbuffer
invalidate and busy by removing unecesarry signature argument for ring.

It was unsed on mark_fb_busy and only used on fb_obj_invalidate for the
same ORIGIN_CS usage. So let's clean it a bit
