[M] Change in flashrom[master]: flashrom: rewrite flashbuses_to_text()

Hello build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/flashrom/+/73039 to look at the new patch set (#3). Change subject: flashrom: rewrite flashbuses_to_text() ...................................................................... flashrom: rewrite flashbuses_to_text() The previous implementation had no error handling, as a result the flashrom could crash if the computer ran out of memory. The new version returns NULL in such cases. Also rewrite lots of `if` conditions to one cycle, store a name of buses in an array. The caller always expected a non-null value, so change its behavior to handle possible null value. As far as `printf()` and `free()` can handle null pointers, do nothing with such callers.
