  "message": "libata: fix PMP initialization\n\nCommit 842faa6c1a1d6faddf3377948e5cf214812c6c90 fixed error handling\nduring attach by not committing detected device class to dev-\u003eclass\nwhile attaching a new device.  However, this change missed the PMP\nclass check in the configuration loop causing a new PMP device to go\nthrough ata_dev_configure() as if it were an ATA or ATAPI device.\n\nAs PMP device doesn\u0027t have a regular IDENTIFY data, this makes\nata_dev_configure() tries to configure a PMP device using an invalid\ndata.  For the most part, it wasn\u0027t too harmful and went unnoticed but\nthis ends up clearing dev-\u003eflags which may have ATA_DFLAG_AN set by\nsata_pmp_attach().  This means that SATA_PMP_FEAT_NOTIFY ends up being\ndisabled on PMPs and on PMPs which honor the flag breaks hotplug\nsupport.\n\nThis problem was discovered and reported by Ethan Hsiao.\n\nSigned-off-by: Tejun Heo \u003ctj@kernel.org\u003e\nReported-by: Ethan Hsiao \u003cethanhsiao@jmicron.com\u003e\nCc: stable@kernel.org\nSigned-off-by: Jeff Garzik \u003cjgarzik@redhat.com\u003e\n",
