[03/19] clk: meson: only one loop index is necessary in probe

Commit Message

Jerome Brunet Jan. 31, 2018, 6:09 p.m. UTC

We don't need several loop index variables in the probe function
This is far from being critical but since we are doing a vast
rework of meson clock controllers, now is the time to lower the
entropy a bit
