Kim, Milo 1430e17844 drivers/rtc/rtc-tps65910.c: fix invalid pointer access on _remove() 
The tps65910_rtc data is registered as the platform driver data in
_probe(= ).  Therefore the tps65910_rtc should be used on unregistering
the rtc device.  And device pointer should be retrieved from the
platform_device structure.

This patch fixes the below oops:

 Unable to handle kernel NULL pointer dereference at virtual address 00000008
