I don't like this goto.
It suggests that calling arche_platform_set_wake_detect_state(arche_pdata, WD_STATE_COLDBOOT_TRIG);
is a part of a shared exit path when that is not true so it is sort of
lying to the reader and making things harder to understand.
Unlocking is shared. goto unlock is fine. But that doesn't help with
the very long lines. (I am not saying that goto unlock is a worthwhile
patch to send but I would definitely have found it tolerable).
