------------------------------------------------------
Subject: rtc: pxa27x/pxa3xx driver fixes, revised
From: Alessandro Zummo <a.zummo@xxxxxxxxxxxx>
Small fixes for the pxa27x/pxa3xx driver
- use platform_driver_probe
- fixed exit paths
- fixed probe sequence
- added missing include
- using linux/io.h instead of asm/io.h
