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>
