Ah, okay. With this assumption, the patch makes sense. Still, the patch
description should refer more to the above statement and not to watchdogs IMHO.

I meant fixing the watchdog in hardware: If the watchdog pulls the right
#RESET, the flash will be in read-mode by default. If not, this is an important
hardware issue.
