[PATCH v2 07/16] clk: simplify clk_core_get_parent_by_index()

From: Masahiro Yamada
Date: Mon Dec 28 2015 - 05:12:18 EST


Drop the "if (!core->parents)" case and refactor the function a bit
because core->parents is always allocated. (Strictly speaking, it is
ZERO_SIZE_PTR if core->num_parents == 0, but such a case is omitted
by the if-conditional above.)
