[PATCH] CLKDEV: return from clk_find as soon as we get maching clk

[viresh.kumar@st.com (Viresh KUMAR)]

clk_find function looks for clock with matching dev_id and con_id.
We should return from clk_find as soon as we get a clock with matching dev_id
and con_id. This can be done by comparing variable "match" with 3.
