Commit b7270c69 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'rtc-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "A great rework of the isl12022 driver makes up the bulk of the
  changes. There is also an important fix for CMOS and then the usual
  small fixes:

   - switch to devm_clk_get_enabled() where relevant

   - cmos: event handler registration fix

   - isl12022: code improvements"
