From: Stefan Richter Date: Wed, 29 Mar 2006 01:03:55 +0000 (-0500) Subject: sbp2: misc debug logging cleanups X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d024ebc67eaa6bb7abca2e3061cb257a1587fa30;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git sbp2: misc debug logging cleanups - move call of scsi_print_command from sbp2_send_command to the beginning of sbp2_queue_command to show also commands which are not sent - put sbp2's name into scsi_print_sense - use __FUNCTION__ in log messages - remove a few less useful log messages and comments Signed-off-by: Stefan Richter Signed-off-by: Jody McIntyre --- diff --git a/drivers/ieee1394/sbp2.c b/drivers/ieee1394/sbp2.c index eb7106b8fd0a..2c765ca5aa50 100644 --- a/drivers/ieee1394/sbp2.c +++ b/drivers/ieee1394/sbp2.c @@ -214,6 +214,7 @@ static u32 global_outstanding_dmas = 0; #endif #define SBP2_ERR(fmt, args...)
