[PATCH v2 2/4] clk: Use 'parent' to shorten lines in __clk_core_init()

From: Stephen Boyd
Date: Wed Feb 05 2020 - 18:28:08 EST


Some lines are getting long in this function. Let's move 'parent' up to
the top of the function and use it in many places whenever there is a
parent for a clk. This shortens some lines by avoiding core->parent->
indirections.
