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

Pull clk fixes from Stephen Boyd:
 "A small set of fixes for clk drivers.

  One to fix a DT refcount imbalance, two to mark some Amlogic clks as
  critical, and one final one that fixes a clk name for the Qualcomm
  driver merged this cycle"

* tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux:
  clk: qcom: gcc: Fix board clock node name
  clk: meson: axg: mark fdiv2 and fdiv3 as critical
  clk: meson-gxbb: set fclk_div3 as CLK_IS_CRITICAL
  clk: fixed-factor: fix of_node_get-put imbalance
