Subject[PATCH 4.0 051/105] i2c: s3c2410: fix oops in suspend callback for non-dt platforms
Date
4.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vasily Khoruzhick <anarsoul@gmail.com>

commit 8d487a43c36b54a029d74ad3b0a6a9d1253e728a upstream.

Initialize sysreg by default, otherwise driver will crash in suspend
callback when not using DT.
