From bd98e6ae7160d5a4fc013266183506068227dd79 Mon Sep 17 00:00:00 2001 From: "Park, Aiden" Date: Tue, 20 Aug 2019 16:47:42 +0000 Subject: [PATCH] dm: scsi: Scan the actual number of ports The scsi_scan_dev() is looping over the number of uc_plat->max_id. The number of actual ports a AHCI controller has can be greater than max_id. Update uc_plat->max_id to make SCSI scan all detected ports.
