From: Abdiel Janulgue Date: Thu, 5 Mar 2020 20:42:58 +0000 (+0000) Subject: drm/i915/phys: unconditionally call release_memory_region X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=64dc802aa5accfe36d431814ffdf15303b7f7b2b;p=linux.git 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.
