Wolfram,
I think there is a problem with your patch:
commit 92d921c5def1a7b1411bc54859c0771b2cf2c08d
rtc: ep93xx: Initialize drvdata before registering device
You are calling platform_set_drvdata() with rtc == NULL at best, it
could possibly also be garbage. The rtc variable is allocated in
rtc_device_register().
A couple printk's prove this out:
ep93xx_rtc_probe: before platform_set_drvdata -> rtc: (null)
ep93xx-rtc ep93xx-rtc: rtc core: registered ep93xx-rtc as rtc0
ep93xx_rtc_probe: after rtc_device_register -> rtc: c4789c00
