Yeah, that would be better.
Even better would be just to delete all of this debug crud from these
drivers. Almost all of the messages are there from when the developer
originally wrote the driver, trying to figure out what was going on.
>From what I have seen, in doing all of these cleanups, is that the need
for maybe a few debug lines that can be used if users have issues, but
the majority are just useless.
But, as I'm not the author or maintainer of these drivers, I'll be nice
and just leave them in, all I want to do is get rid of the old, foolish,
macros for debugging and use the proper dynamic debug code that works so
much better.
So I'll leave this change alone, and if someone wants to do the cleanup
better, the 3 liner above is fine with me to add later.
