Hello build bot (Jenkins), Jason Glenesk, Raul Rangel, Marshall Dawson, Zheng Bao, Nikolai Vyssotski, Fred Reitberger, Rob Barnes, Karthik Ramasubramanian, Karthikeyan Ramasubramanian, Karthikeyan Ramasubramanian, Felix Held,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/62482

to look at the new patch set (#8).

Change subject: amdfwtool: Clear struct match before regular expression matching
......................................................................

amdfwtool: Clear struct match before regular expression matching

If it is not cleared and the number of strings is fewer than last
iteration, the match[3] will keep the last value, which actually
should be empty.

Add assert to make sure the level is a legal value.
