but what you're suggesting is not equivalent.  i submitted that patch
to fix what *seems* to be an obvious, innocuous typo, to bring that
one header file into sync with the rest of the source tree, nothing
more.

if all debugging should now use either of pr_debug() or dev_dbg(),
that's fine but i notice that both of those macros will be defined
only if "DEBUG" is defined, not "DEBUG_DRIVER".  so making the change
you suggest would *not* be a trivial change.

what's the current standard for debugging directives in the kernel?
