Subject: regulator: Remove NULL test before calling regulator_unregister()
X-Git-Tag: v3.12-rc1~994^2~21^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=020501f1a0911af70873e4d3d122b2e1889ccd03;p=kernel%2Fkernel-generic.git

regulator: Remove NULL test before calling regulator_unregister()

It's safe to call regulator_unregister() with NULL, thus remove the NULL test
before regulator_unregister() calls.
