[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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Dave Jones <davej@redhat.com>
