From d968e99488c4b08259a324a89e4ed17bf36561a4 Mon Sep 17 00:00:00 2001 From: Adrian Hunter adrian.hunter@intel.com Date: Fri, 24 Oct 2025 11:59:17 +0300 Subject: [PATCH] scsi: ufs: ufs-pci: Set UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE for Intel ADL
Link startup becomes unreliable for Intel Alder Lake based host controllers when a 2nd DME_LINKSTARTUP is issued unnecessarily. Employ UFSHCD_QUIRK_PERFORM_LINK_STARTUP_ONCE to suppress that from happening.
