Merge tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk fix from Stephen Boyd: "One fix for the composite clk that broke when we changed this clk type to use the determine_rate instead of round_rate clk op by default. This caused lots of problems on Rockchip SoCs because they heavily use the composite clk code to model the clk tree" * tag 'clk-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux: clk: composite: Also consider .determine_rate for rate + mux composites
