The commit message need a little bit improvement.  Something like:

Since the interrupt pin for RTC DS1374 is not connected to the CPU on
T4240RDB, remove
the interrupt property from the device tree.

This also fix the following warning for hwclock.util-linux:
  $ hwclock.util-linux
   hwclock.util-linux: select() to /dev/rtc0
   to wait for clock tick timed out
