Subject: [PATCH] scsi: mpt3sas: disable ASPM for mpt3sas / SAS3.0
Date: Thu, 25 Mar 2021 12:51:29 -0700 [thread overview]
Message-ID: <1616701889-77537-1-git-send-email-ice799@gmail.com> (raw)
Noticed commit ffdadd68af5a ("scsi: mpt3sas: disable ASPM for MPI2
controllers") disables ASPM for SAS-2.0 HBAs, but this change was not
replicated for SAS-3.0 HBAs. This change replicates this behavior.
