Merge tag 'v4.7-rockchip-clk2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into clk-next

Pull some checkpatch silencers from Heiko Stuebner:

Fix quite some checkpatch warnings in the newly added
rk3399 header and also in the clock code itself.

* tag 'v4.7-rockchip-clk2' of git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip:
  clk: rockchip: fix checkpatch warning in core code
  clk: rockchip: drop unnecessary header comment
  clk: rockchip: reign in some overly long lines in the rk3399 controller
  clk: rockchip: fix checkpatch errors in rk3399 dt-binding header
