[PATCH 1/6] scsi: pm80xx: Log some HW events by default

From: Pranav Prasad
Date: Tue Apr 18 2023 - 15:01:56 EST

From: Akshat Jain <akshatzen@xxxxxxxxxx>

Log the following hw_event logs under EVENT log severity
to help debug disk issues:
HW_EVENT_LINK_ERR_INVALID_DWORD
HW_EVENT_LINK_ERR_DISPARITY_ERROR
HW_EVENT_LINK_ERR_CODE_VIOLATION
HW_EVENT_LINK_ERR_LOSS_OF_DWORD_SYNCH
HW_EVENT_LINK_ERR_PHY_RESET_FAILED
HW_EVENT_INBOUND_CRC_ERROR
HW_EVENT_PHY_ERROR
HW_EVENT_SAS_PHY_UP
HW_EVENT_SATA_PHY_UP
HW_EVENT_SATA_SPINUP_HOLD
HW_EVENT_PHY_DOWN
HW_EVENT_PORT_INVALID
HW_EVENT_MALFUNCTION
HW_EVENT_PORT_RESET_TIMER_TMO
HW_EVENT_PORT_RECOVERY_TIMER_TMO
HW_EVENT_HARD_RESET_RECEIVED
HW_EVENT_ID_FRAME_TIMEOUT
HW_EVENT_PORT_RECOVER
