[PATCH 20/27] Remove scsi_show_result()

Hannes Reinecke
2014-10-24T12:27:18Z

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
