From ca250b6017910ca6edca4cbd6eaa7452a13b5c03 Mon Sep 17 00:00:00 2001 From: Marc Dietrich Date: Sat, 27 Jul 2013 18:20:58 +0200 Subject: [PATCH] staging: nvec: re-enable the clock on resume On resume the slave controller is reinitialized. The tegra i2c master controller disables the clock at the end of the initialiation, propably to save some power, and enables it again on each transfer. We don't do this yet and also forgot to enable the clock on resume. Fix this copy-paste error by not disabling the clock after initialization. This didn't striked us yet because suspend/resume hasn't landed in mainline yet, but will soon.
