[PATCH 03/10] hpsa: combine hpsa_scsi_detect and hpsa_register_scsi
From: Stephen M. Cameron
Date: Thu Jan 19 2012 - 15:12:23 EST
From: Stephen M. Cameron <scameron@xxxxxxxxxxxxxxxxxx>
hpsa_register_scsi just calls hpsa_scsi_detect. Move
the guts of hpsa_scsi_detect into hpsa_register_scsi and
get rid of hpsa_scsi_detect.
