From 0b259dc2e849183dfea604fa137bb616e09b319a Mon Sep 17 00:00:00 2001 From: Aaron Durbin Date: Tue, 20 May 2014 06:01:38 -0600 Subject: [PATCH] power: Explicitly select pmic device's bus The current pmic i2c code assumes the current i2c bus is the same as the pmic device's bus. There is nothing ensuring that to be true. Therefore, select the proper bus before performing a transaction.
