From: Thomas Hellstrom Date: Fri, 31 Oct 2014 08:54:22 +0000 (+0100) Subject: drm/vmwgfx: Fix hash key computation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0468ab5b791b0d55a7158b70f555157c8d79d0fb;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git drm/vmwgfx: Fix hash key computation The hash key computation in vmw_cmdbuf_res_remove incorrectly didn't take the resource type into account, contrary to all the other related functions. This becomes important when the cmdbuf resource manager handles more than one resource type.
