Subject: [PATCH v2] USB: remove dbg() usage in USB networking drivers

From: Greg Kroah-Hartman <[email-masked]>
Date: Wed, 19 Sep 2012 20:46:14 +0100

From: Greg Kroah-Hartman <[email-masked]>

The dbg() USB macro is so old, it predates me.  The USB networking drivers are
the last hold-out using this macro, and we want to get rid of it, so replace
the usage of it with the proper netdev_dbg() or dev_dbg() (depending on the
context) calls.

Some places we end up using a local variable for the debug call, so also
convert the other existing dev_* calls to use it as well, to save tiny amounts
of code space.

v2: Addressed review comments from Joe Perches

Again, I am glad to take this in the usb-next tree if wanted, whatever is
easiest.
