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
