OMAP: PM: SmartReflex: Add missing IS_ERR test
Function _sr_lookup, defined in the same file, returns ERR_PTR not NULL in
an error case.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
identifier f;
@@
f(...) { ... return ERR_PTR(...); }
@@
identifier r.f, fld;
expression x;
statement S1,S2;
@@
x = f(...)
... when != IS_ERR(x)
(
if (IS_ERR(x) ||...) S1 else S2
|
*x->fld
)
// </smpl>
