Thanks, when I looked at it last night, it seems to me that you also
need to patch the following drivers:

drivers/regulator/88pm8607.c
drivers/regulator/da9052-regulator.c
drivers/regulator/max8997-regulator.c
drivers/regulator/s5m8767.c

since they all define their array of regulators using uppercase, and
then later match that using the same logic that
drivers/regulator/mc13xxx-regulator-core.c does.
