X-Git-Tag: next-20130527~8^2^14~3
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f0c6f7a3ab6e25de867c2a13c3cd4b17526a4ade;p=karo-tx-linux.git

ARM: shmobile: bockw: add dummy regulators for SMSC

SMSC driver will try to get regulator if .config had CONFIG_REGULATOR,
and, shmobile_defconfig has it.
SMSC driver on Bock-W board will be failed if it doens't have
dummy regulator settings.
