Chris Wilson acb868d3d7 drm/i915: Disallow preallocation of requests ... The intention was to allow the caller to avoid a failure to queue a request having already written commands to the ring. However, this is a moot point as the i915_add_request() can fail for other reasons than a mere allocation failure and those failure cases are more likely than ENOMEM. So the overlay code already had to handle i915_add_request() failures, and due to commit 3bb73aba1e Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Fri Jul 20 12:40:59 2012 +0100 drm/i915: Allow late allocation of request for i915_add_request() the error handling code in intel_overlay.c was subject to causing double-frees, as found by coverity. Rather than further complicate i915_add_request() and callers, realise the battle is lost and adapt intel_overlay.c to take advantage of the late allocation of requests. v2: Handle callers passing in a NULL seqno. v3: Ditto. This time for sure.
