Subject: [PATCH 3/7] drm/i915: clear the FPGA_DBG_RM_NOCLAIM bit at driver init
Date: Fri, 25 Jan 2013 18:57:38 -0200	[thread overview]
Message-ID: <1359147462-3902-4-git-send-email-przanoni@gmail.com> (raw)
In-Reply-To: <1359147462-3902-1-git-send-email-przanoni@gmail.com>

From: Paulo Zanoni <paulo.r.zanoni@intel.com>

Otherwise, if the BIOS did anything wrong, our first I915_{READ,WRITE}
will give us "unclaimed regsiter" messages.
