Subject: [PATCH v2 10/12] drm/i915: Clean up intel_get_dram_info() a bit
Date: Wed,  6 Mar 2019 22:35:49 +0200	[thread overview]
Message-ID: <20190306203551.24592-11-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20190306203551.24592-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Remove the pointless zero initialization of bunch of things
(the thing is kzalloc()ed).

Also throw out the mostly useless on-stack string. I think
it'll be clear enough from the logs that 0 means unknown.
