[CPUFREQ] s5pv210-cpufreq.c: Add missing clk_put
The successive calls to clk_get each call clk_put in the case of failure,
but this is not done for subsequent error handling code. The calls to
clk_get are moved to the end of the function, and appropriate gotos are
added.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)
// <smpl>
@r exists@
expression e1,e2;
statement S;
@@
e1 = clk_get@p1(...);
... when != e1 = e2
when != clk_put(e1)
when any
if (...) { ... when != clk_put(e1)
when != if (...) { ... clk_put(e1) ... }
* return@p3 ...;
} else S
// </smpl>
