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 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
