Subject: [PATCH v2 0/3] clk: Some fixes for the per-user clk API changes.

Hello,

This is a v2 of a series to fix some issues found on linux-next after the
per-user clk API changes were introduced. Booting an Exynos5420 Peach Pit
Chromebook and using a composite clock makes the system to crash due a
NULL pointer dereference error.

A previous version of the series is [0] and this addresses issues pointed
out by Stephen Boyd.

This series is composed of the following patches:

Javier Martinez Canillas (3):
  clk: Don't dereference parent clock if is NULL
  clk: Add __clk_hw_set_clk helper function
  clk: Replace explicit clk assignment with __clk_hw_set_clk
