Subject: [PATCH 1/1] usbnet: allow type check of devdbg arguments in non-debug build
Date: Mon, 15 Sep 2008 16:47:44 +0100 [thread overview]
Message-ID: <1221493664-544-1-git-send-email-steve.glendinning@smsc.com> (raw)
improve usbnet's devdbg to always type-check diagnostic arguments,
like dev_dbg (device.h). This makes no change to the resulting size of
usbnet modules.
