At least from a correctness perspective only the characters / and \0
are forbidden, as well as any existing filenames like . and ..
Generally it is not a great idea to restrict things too much because
it can block the full use of UTF-8 for non-English languages.
However, I also think the sysfs in this driver is far too elaborate,
the time to complain was before this was all merged
unfortunately. Given that it is a simple enough bug fix it may as well
go ahead as-is.
