From 4894fbcce856635c9ab79f44e50826e86bb92110 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?C=C3=A9dric=20Le=20Goater?= Date: Thu, 9 May 2019 14:33:44 +0200 Subject: KVM: PPC: Book3S: Remove useless checks in 'release' method of KVM device MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is no need to test for the device pointer validity when releasing a KVM device.
