Or maybe you could develop an extension for printk() format that
would dump strings of the given length?  Something like %pM, but
with an extra argument (and make sure it would not trigger a gcc
warning). This way, everybody would benefit.

I don't think it would be a noticeable benefit. On the other hand
vsnprintf() is hugely overloaded by many "extensions" to the C99
variant.

I looked at the code, and it seems very little is needed to support
"%*pM"

Please rethink whether it's helpful to send such "fixes" for old and
little maintained drivers.

Last copyright is 2010, TODO list actually suggests to remove hex2str
at all.

I don't know where it's written, but I think it's a good idea,
especially if there is a better alternative available for all drivers.
