[PATCH 9/10] arch/arm/mach-omap2/clock.c: add missing clk_put

[julia@diku.dk (Julia Lawall)]

From: Julia Lawall <julia@diku.dk>

Add missing call to clk_put.

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 at p1(...);
... when != e1 = e2
    when != clk_put(e1)
    when any
if (...) { ... when != clk_put(e1)
               when != if (...) { ... clk_put(e1) ... }
* return at p3 ...;
 } else S
// </smpl>
