Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk fixes from Stephen Boyd:
 "A handful of driver fixes.

  The sunxi fixes are for an incorrect clk tree configuration and a bad
  frequency calculation. The other two are fixes for passing the wrong
  pointer in drivers recently converted to clk_hw style registration"
