Merge tag 'regulator-fix-v6.2-rc1' of git://git./linux/kernel/git/broonie/regulator

Pull regulator fixes from Mark Brown:
 "Two core fixes here, one for a long standing race which some Qualcomm
  systems have started triggering with their UFS driver and another
  fixing a problem with supply lookup introduced by the fixes for devm
  related use after free issues that were introduced in this merge
  window"

* tag 'regulator-fix-v6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: core: fix deadlock on regulator enable
  regulator: core: Fix resolve supply lookup issue
