Subject: iio:dac:m62332: shutdown on remove
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=847e3928de0998883219d7052cf4c049c21966e9;p=deliverable%2Flinux.git

iio:dac:m62332: shutdown on remove

The regulator framework requests to balance regulator_enable() calls with
regulator_disable() calls. To meet this requirement, set channels to 0 on
remove, which implies a regulator_disable() call in case that channel was
enabled.
