From: John Harrison Date: Fri, 29 May 2015 16:44:00 +0000 (+0100) Subject: drm/i915: Update ring->add_request() to take a request structure X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ee044a8863de58044cb370c23f97b9b68b33e47b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Update ring->add_request() to take a request structure Updated the various ring->add_request() implementations to take a request instead of a ring. This removes their reliance on the OLR to obtain the seqno value that the request should be tagged with.
