[ARM] arch/arm/common/sa1111.c: Correct error handling code
If it is reasonable to apply PTR_ERR to the result of calling clk_get, then
that result should first be tested with IS_ERR, not with !.
The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
expression E,E1;
@@
if (
- E == NULL
+ IS_ERR(E)
) { <+... when != E = E1
PTR_ERR(E)
...+> }
// </smpl>
