[PATCH] isdn4linux: Siemens Gigaset drivers: logging usage
With Hansjoerg Lipp <hjlipp@web.de> 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. Signed-off-by: Hansjoerg Lipp <hjlipp@web.de> Signed-off-by: Tilman Schmidt <tilman@imap.cc> Cc: Karsten Keil <kkeil@suse.de> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
