+Subject: Revert "drm/amd/amdgpu: Fix potential ioremap() memory leaks in amdgpu_device_init()"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit

+From: Ma Jun <Jun.Ma2@amd.com>
+
+commit 03c6284df179de3a4a6e0684764b1c71d2a405e2 upstream.
+
+This patch causes the following iounmap erorr and calltrace
+iounmap: bad address 00000000d0b3631f
+
+The original patch was unjustified because amdgpu_device_fini_sw() will
+always cleanup the rmmio mapping.
+
+This reverts commit eb4f139888f636614dab3bcce97ff61cefc4b3a7.
