Hi Hauke,

This patch series caused a regression in one of our smoketest machines
last night. I have not looked at the exact patch causing it (suspect
2/9). The failure happens on a BCM43224 chip with external SPROM. Here
is the log info:

I suspect it tries reading OTP instead of the external SPROM.
