From: Stephen Boyd Date: Mon, 22 Feb 2016 19:12:47 +0000 (-0800) Subject: usb: dwc3: Remove impossible check for of_clk_get_parent_count() < 0 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3d755dcc20dd452b52532eca17da40ebbd12aee9;p=linux-beck.git usb: dwc3: Remove impossible check for of_clk_get_parent_count() < 0 The check for < 0 is impossible now that of_clk_get_parent_count() returns an unsigned int. Simplify the code and update the types.
