From 4a770ccaae1fd2ecad9dcc3f7942d3b163ecf362 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 14 Sep 2012 15:08:30 -0700 Subject: [PATCH] USB: serial: mct_u232.c: remove dbg() usage dbg() was a very old USB-serial-specific macro. This patch removes it from being used in the driver and uses dev_dbg() instead.
