[PATCH v4 2/3] clk: s2mps11: Remove useless check for clk_table

From: Krzysztof Kozlowski
Date: Wed May 21 2014 - 07:24:14 EST


There is no need for checking if 'clk_table' is not NULL twice (first
after allocation and second at the end of probe()). Also move allocation
of this 'clk_table' to probe from s2mps11_clk_parse_dt as this is
logical place for it.
