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

Pull clk fixes from Stephen Boyd:

 - build fix to export the clk_bulk_prepare() symbol

 - suspend fix for Samsung Exynos SoCs where we need to keep clks on
   across suspend

 - two critical clk markings for clks that shouldn't ever turn off on
   Rockchip SoCs

 - a fix for a copy-paste mistake on Rockchip rk3128 causing some clks
   to touch the same bit and trample over one another
