[PATCH] iowarrior: Convert local dbg macro to dev_dbg

From: Joe Perches
Date: Tue May 20 2014 - 16:09:43 EST


Use a more standard logging style.

Add terminating newlines to formats.
Remove __func__ as that can be added via dynamic debug.
Remove now unnecessary debug module parameter.
Remove the dbg macro too.

compiled/untested, no hardware.
