Subject: regulator: pfuze100: Don't allocate an invalid gpio
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fe788b09552d1ea318d80d50962d3af69fbb0dbc;p=deliverable%2Flinux.git

regulator: pfuze100: Don't allocate an invalid gpio

Previously, the PFUZE100 would try to allocate gpio0 io0 because
config.ena_gpio defaults to 0, which can be a valid GPIO.  To prevent this
from happening, set this parameter to -EINVAL.
