drm/i915: Extract ring init from hw_init
The ring initialization will differ a bit in upcoming generations, and this split will prepare the code for what's needed. This patch also fixes a bug introduced in: commit 99433931950f33039d9e1a52b4ed9af3f1b58e84 Author: Mika Kuoppala <mika.kuoppala@linux.intel.com> Date: Tue Jan 22 14:12:17 2013 +0200 drm/i915: use gem_set_seqno() on hardware init After doing the extraction, the bad error handling became obvious. I acknowledge that this should be two patches, but it's a pretty small/trivial patch. If requested, I can certainly do the fix as a distinct patch. v2: Should be cleanup blt, not init blt on failure (Chris) v3: Forgot to git add on v2 Cc: Mika Kuoppala <mika.kuoppala@linux.intel.com> Reviewed-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ben Widawsky <ben@bwidawsk.net> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
