From: Axel Lin Date: Wed, 4 Apr 2012 11:52:35 +0000 (+0800) Subject: regulator: Fix rc5t583_regulator_probe error handling X-Git-Tag: v3.5-rc1~177^2~58^3~60 X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=a69df8a14ae7b891ee22f0e4c081f3ff65c0640f;p=~emulex%2Finfiniband.git regulator: Fix rc5t583_regulator_probe error handling 1. regulator_register returns ERR_PTR on error, thus use IS_ERR to check the return value. 2. Fix off-by-one for unregistering the registered regulator. Current code does not unregister regs[0].rdev in clean_exit.
