Date: Thu, 19 Jun 2014 19:07:15 +0200 From: Konrad Zapalowicz <bergo.torino@...il.com> To: daniel.vetter@...ll.ch Cc: jani.nikula@...ux.intel.com, airlied@...ux.ie, intel-gfx@...ts.freedesktop.org, dri-devel@...ts.freedesktop.org, linux-kernel@...r.kernel.org, Konrad Zapalowicz <bergo.torino@...il.com> Subject: [PATCH v2] drivers/i915: Fix unnoticed failure of init_ring_common() This commit add check for return value of init_ring_common() in the init_render_ring(). Now, when failure is detected the error code is propagated to the caller instead of being ignored.
