[PATCH 7/9] clk: ti: Update for of_clk_get_parent_count() returning unsigned int

From: Stephen Boyd
Date: Mon Feb 22 2016 - 15:56:44 EST


Change the types here to unsigned int instead of int and update
the checks for == 0 instead < 1 to be more explicit about what's
going on now that of_clk_get_parent_count() has changed return
types.
