Subject: clk: s2mps11: Remove useless check for clk_table
X-Git-Tag: next-20140530~7^2~8
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7002483c7b28a808d2bd4366b00c48911688c768;p=karo-tx-linux.git

clk: s2mps11: Remove useless check for clk_table

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.
