From 4c567a9d0e009c998125d549dc53ab0d21724a55 Mon Sep 17 00:00:00 2001 From: Jolly Shah Date: Mon, 25 Nov 2024 13:33:43 -0800 Subject: scsi: pm80xx: Use dynamic tag numbers for PHY start and stop Other commands were not aware if tag 0x01 was in use or not which meant multiple commands could share the same tag number. Prevent tag 0x01 from being used by multiple commands at the same time.
