From 5cd78de5267f36c090043836649b31c12533bbe9 Mon Sep 17 00:00:00 2001 From: Oded Gabbay Date: Thu, 20 Nov 2014 16:14:56 +0200 Subject: [PATCH] amdkfd: add __iomem attribute to doorbell_ptr This patch was done due to sparse warning. It changes the definition of doorbell_ptr in queue_properties to be with __iomem attribute, so it would match the type which the doorbell module functions are returning.
