From 3300fb4f88688029fff8dfb9ec0734f6e4cba3e7 Mon Sep 17 00:00:00 2001 From: Jean Delvare Date: Mon, 5 Nov 2012 21:54:39 +0100 Subject: hwmon: (w83627ehf) Force initial bank selection Don't assume bank 0 is selected at device probe time. This may not be the case. Force bank selection at first register access to guarantee that we read the right registers upon driver loading.
