From d13c46c67e546bb1dc1c4dc7c43e388d0119276b Mon Sep 17 00:00:00 2001 From: Russell King Date: Mon, 3 Mar 2014 14:49:51 +0000 Subject: DRM: armada: fix use of kfifo_put() The kfifo_put() API changed in 498d319bb512 (kfifo API type safety) which now results in the wrong pointer being added to the kfifo ring, which then causes an oops. Fix this.
