PM / OPP / clk: Remove unnecessary OOM message
This patch reduces the kernel size by removing error messages that duplicate
the normal OOM message.
A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr)
@@
identifier f,print,l;
expression e;
constant char[] c;
@@
e = \(kzalloc\|kmalloc\|devm_kzalloc\|devm_kmalloc\)(...);
if (e == NULL) {
<+...
- print(...,c,...);
... when any
(
goto l;
|
return ...;
)
...+> }
