From eac0b0c76ff904e66b115777cb3e40a98cca6764 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Fri, 24 Apr 2015 13:18:20 +0200 Subject: advansys: use host_reset The advansys_reset() function is actually a host reset, not a bus reset. And there is no need to have a 'last_reset' value; the same value exists in struct Scsi_Host.
