Subject: clk: remove redundant negative index check in of_clk_get_parent_name()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c736c4e11e9def555482f3f626254594d3f11f9c;p=linux-beck.git

clk: remove redundant negative index check in of_clk_get_parent_name()

This if-block can be dropped because the of_parse_phandle_with_args()
in the following line returns -EINVAL for negative index.
