[PATCH] PM / devfreq: rk3399_dmc: Remove explictly regulator_put call in .remove

[Axel Lin]

Current code uses devm_regulator_get() in .probe so a regulator_put() will
be automatically called when unload the module. Remove the explictly
regulator_put() call and then we can also remove rk3399_dmcfreq_remove().

Sign-off-by is for three cases:
(1) You send a patch you created.
(2) You send a patch from someone else (ie. you're not the author of it).
(3) You apply a patch.

Otherwise, please use Acked-by (and I'm going to add that to this
patch and to the other one you responded to with an S-o-b).

Thanks,
Rafael
