Subject: regulator: stubs: Make stub regulator_get_voltage() return an error
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=08aed2f6fb09c9f8efc9258c152072ed614db226;p=deliverable%2Flinux.git

regulator: stubs: Make stub regulator_get_voltage() return an error

Returning 0 isn't useful, it's not even meaningful if there is a real
regulator there.
