4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Johan Hovold <johan@xxxxxxxxxx>
commit 5c8b84f410b3819d14cb1ebf32e4b3714b5a6e0b upstream.
Do not set the system power-off callback and omap power-off rtc pointer
until we're done setting up our device to avoid leaving stale pointers
around after a late probe error.
Fixes: 97ea1906b3c2 ("rtc: omap: Support ext_wakeup configuration")
