drm/radeon: adjust tested variable
commit 3a61b527b4e1f285d21b6e9e623dc45cf8bb391f upstream. Check the variable that was most recently initialized. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x, y, f, g, e, m; statement S1,S2,S3,S4; @@ x = f(...); if (\(<+...x...+>\&e\)) S1 else S2 ( x = g(...); | m = g(...,&x,...); | y = g(...); *if (e) S3 else S4 ) // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Reviewed-by: Christian K├Ânig <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
