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

Pull clk fixes from Stephen Boyd:
 "A few clk driver fixes for the merge window to fix the build and boot
  on some SoCs.

   - Initialize struct clk_init_data in the TI da8xx-cfgchip driver so
     that stack contents aren't used for things like clk flags leading
     to unexpected behavior

   - Don't leak stack contents in a debug print in the new Sophgo clk
     driver

   - Disable the new T-Head clk driver on 32-bit targets to fix the
     build due to a division

   - Fix Samsung Exynos4 fin_pll wreckage from the clkdev rework done
     last cycle by using a struct clk_hw directly instead of a struct
     clk consumer"
