This patch fixes offset for Format-2 data structure for Report ID Acquisition. This caused driver to set remote_nport_id to 0x0000 in N2N configuration. In a scenario where initiator's WWPN is higher than target's WWPN, driver will assign 0x00 as target nport-id, which results into login failure.

Session is stuck if driver sees FW has received a PRLI. Driver allows FW to finish with processing of PRLI by checking back with FW at a later time to see if the PRLI has finished.

During cable pull test case, if the port is disconnected for time larger than devloss timeout, driver does not mark path offline. In such case, instead of notifying SCSI-ML of loop down, driver goes into endless loop of device relogin because defer flag is set. With newer handling of device relogin in driver discovery, defer flag is now redundant. This patch removes defer flag and cleans up code handling port lost indication to SCSI-ML.

During suspend flow, interrupt shall be disabled before disabling clocks to avoid potential system hang due to accessing host registers after host clocks are disabled. For example, if an interrupt comes with IRQF_IRQPOLL flag configured with the misrouted interrupt recovery feature enabled, ufshcd ISR may be triggered even if nothing shall be done for UFS. In this case, system hang may happen if UFS interrupt status register is accessed with host clocks disabled.

Since ufshcd irq resource is allocated with the device resource management aware IRQ request implementation, we don't really need to free up irq during suspend, disabling it during suspend and reenabling it during resume should be good enough.

During power mode change, PACP_PWR_Req frame sends PAPowerModeUserData parameters (and they are considered valid by device if Flags[4] - UserDataValid bit is set in the same frame). Currently we don't set these PAPowerModeUserData parameters and hardware always sets UserDataValid bit which would clear all the DL layer timeout values of the peer device after the power mode change. This change sets the PAPowerModeUserData[0..5] to UniPro specification recommended default values, in addition we are also setting the relevant DME_LOCAL_* timer attributes as required by UFS HCI specification.

UFS standard requires DBD field to be set to 1 in MODE SENSE(10). Some card vendors are more strict and check the DBD field, hence respond with CHECK_CONDITION (Sense key set to ILLEGAL_REQUEST and ASC set to INVALID FIELD IN CDB). When host sends MODE SENSE for page caching, as a result of the CHECK_CONDITION response, host assumes that the device doesn't support the cache feature and doesn't send SYNCHRONIZE_CACHE commands to flush the device cache. This can result in data corruption in case of sudden power down when there is data stored in the device cache. This patch fixes the DBD field setting as required in UFS standard.

In UFS host reset and restore path, before probe, we stop and start the host controller once. After host controller is stopped, the pending requests, if any, are cleared from the doorbell, but no completion IRQ would be raised due to the hba is stopped. These pending requests shall be completed along with the first NOP_OUT command (as it is the first command which can raise a transfer completion IRQ) sent during probe. Since the OCSs of these pending requests are not SUCCESS (because they are not yet literally finished), their UPIUs shall be dumped. When there are multiple pending requests, the UPIU dump can be overwhelming and may lead to stability issues because it is in atomic context. Therefore, before probe, complete these pending requests right after host controller is stopped and silence the UPIU dump from them.
