It seems to me that the rustfmt.toml in the kernel, don't have a max width for
line. Are you sure that the rustfmt would broke the line for big enough lines?

If you (daniel and miguel) are ok with repeat the `author` field and think that
this is the better option I is happy to make this change. 

I was run the follow command:
grep -rwo 'MODULE_AUTHOR' . | awk -F: '{count[$1]++} END {for (file in count) if (count[file] > 1) print file, count[file]}' | sort -k2 -n > res
for found the modules with more than one MODULE_AUTHOR.
I see that the maximum of MODULE_AUTHOR that is contains in a module is 11. The
marjority have 2 MODULE_AUTHOR. Maybe, repeat the `author` field, is don't a
bad idea.

Thoughs?
