Since v4.3+, CONFIG_REGULATOR_PBIAS should be enabled (for platforms that have PBIAS regulator) in order for MMC1 to work. Add a more verbose print to help enable CONFIG_REGULATOR_PBIAS for users using a olddefconfig or a custom .config. Signed-off-by: Kishon Vijay Abraham I <redacted>
Thanks,applied for next! Kind regards Uffe
