Commit 4a7a7729 authored by Linus Torvalds's avatar Linus Torvalds

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

Pull clk fixes froom Stephen Boyd:
 "A handful of fixes for the stm32mp1 clk driver came in during the
  merge window for the driver that got merged in the merge window.

  Plus a warning fix for unused PM ops and a couple fixes for the meson
  clk driver clk names that went unnoticed with the regmap rework.

  There's also another fix in here for the mux rounding flag which
  wasn't doing what it said it did, but now it does"
