Subject: Re: [PATCH v6 3/6] kernel/reboot.c: export pm_power_off_prepare

Hallo Andrew,
I need your ACK or NACK for this patch.

This function is used to configure external PMIC to interpret
signal which will be triggered by pm_power_off as power off.
Since same signal can be used for stand by, I linked PMIC configuration
with pm_power_off_prepare to avoid possible conflicts.
