From 43a07e48af44c153f960e4a204771d5911e10134 Mon Sep 17 00:00:00 2001 From: Eva Rachel Retuya Date: Tue, 1 Nov 2016 01:04:35 +0800 Subject: [PATCH] staging: iio: ad9832: clean-up regulator 'reg' Rename regulator 'reg' to 'avdd' so as to be clear what regulator it stands for specifically. Additionally, get rid of local variable 'reg' and use direct assignment instead. Update also the goto label pertaining to the avdd regulator during disable.
