Pull regulator fixes from Mark Brown:
 "An addition to MAINTAINERS plus a fix for a nasty bootstrapping
  problem which caused problems when we need to read the voltage of a
  regulator that is not yet available during initialization, we were not
  correctly distinguishing between this case and the case where a
  regulator is put into a bypass mode"

* tag 'regulator-fix-v5.10-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator:
  regulator: defer probe when trying to get voltage from unresolved supply
  MAINTAINERS: Add entry for Qualcomm IPQ4019 VQMMC regulator
