From e8656b02ef353e73d0625302c85026f80958c531 Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Tue, 18 Sep 2012 01:35:12 -0700 Subject: [PATCH] USB: serial: serqt_usb2: 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.
