From 4a324d33bfe95a279d4c7370d84087d3e773e799 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Mon, 4 May 2015 16:05:14 +0200 Subject: [PATCH] drm: simplify master cleanup In drm_master_destroy() we _free_ the master object. There is no reason to hold any locks while dropping its static members, nor do we have to reset it to 0. Furthermore, kfree() already does NULL checks, so call it directly on master->unique and drop the redundant reset-code.
