From 784d5858aac58c06608def862d73ae9a32f5ee23 Mon Sep 17 00:00:00 2001 From: Tilman Schmidt Date: Mon, 10 Apr 2006 22:55:04 -0700 Subject: [PATCH] [PATCH] isdn4linux: Siemens Gigaset drivers: logging usage With Hansjoerg Lipp Improve error reporting of the Gigaset drivers, by using the dev_err/dev_warn/dev_info macros from device.h instead of err/warn/info from usb.h whereever possible. Also rename the private dbg macro to gig_dbg in order to avoid confusion with the macro of the same name in usb.h.
