From 64dc802aa5accfe36d431814ffdf15303b7f7b2b Mon Sep 17 00:00:00 2001 From: Abdiel Janulgue Date: Thu, 5 Mar 2020 20:42:58 +0000 Subject: [PATCH] drm/i915/phys: unconditionally call release_memory_region The release method will undo what we did at creation, and so we shouldn't care if we have pages or not. Fixes a small leak in the mock_phys selftest.
