From ef61329db7b8b4326b1c4e603806b2754fd2a692 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 24 Oct 2014 14:27:00 +0200 Subject: [PATCH] scsi: remove scsi_show_result() Open-code scsi_print_result in sd.c, and cleanup logging to not print duplicate informations. Also remove the call to scsi_show_result() in ufshcd.c to be consistent with other callers of scsi_execute(). With that we can remove scsi_show_result in constants.c Signed-off-by: Hannes Reinecke Reviewed-by: Robert Elliott Signed-off-by: Christoph Hellwig --- drivers/scsi/constants.c | 16 ------------- drivers/scsi/sd.c | 50 ++++++++++++++++++++------------------- drivers/scsi/ufs/ufshcd.c | 4 ++-- include/scsi/scsi_dbg.h | 1 - 4 files changed, 28 insertions(+), 43 deletions(-) diff --git a/drivers/scsi/constants.c b/drivers/scsi/constants.c index 541a8620929c..2893464129b5 100644 --- a/drivers/scsi/constants.c +++ b/drivers/scsi/constants.c @@ -1440,22 +1440,6 @@ const char *scsi_driverbyte_string(int result) } EXPORT_SYMBOL(scsi_driverbyte_string); -void scsi_show_result(int result) -{ - const char *hb_string = scsi_hostbyte_string(result); - const char *db_string = scsi_driverbyte_string(result); - - if (hb_string || db_string) - printk("Result: hostbyte=%s driverbyte=%s\n", - hb_string ?
