[PATCH v1 0/4] rtc: pcf2127: a fix, a cleanup and two questionable features

[Uwe Kleine-KÃnig]

Hello,

the fix and the cleanup should be fine. Patches 3 and 4 are probably
wrong (but still state of the art for other in-tree drivers) because
sysfs_create_file is called too late. See
http://kroah.com/log/blog/2013/06/26/how-to-create-a-sysfs-file-correctly/
for some details.

I failed to find how to do it correctly though:
 - the attributes are device specific, so device_driver::groups is wrong
 - for using the i2c's device group it's too late in .probe
 - the rtc's device is only malloc'd in rtc_device_register and when
   this returns it's already too late again.
 - these are neither class nor bus attributes, so these are ruled out, too.

Uwe Kleine-KÃnig (4):
  rtc: pcf2127: fix reading uninitialized value on RTC_READ_VL ioctl
  rtc: pcf2127: remove useless driver version
  rtc: pcf2127: implement reading battery status bits
  rtc: pcf2127: implement access to nvram
