The current implementation of scsi_vpd_lun_id() uses the designator length
as an implicit measure of priority. This works most of the time, but not
always. For example, some Hitachi storage arrays return this in VPD 0x83:
VPD INQUIRY: Device Identification page
Designation descriptor number 1, descriptor length: 24
designator_type: T10 vendor identification, code_set: ASCII
associated with the Addressed logical unit
vendor id: HITACHI
vendor specific: 5030C3502025
Designation descriptor number 2, descriptor length: 6
designator_type: vendor specific [0x0], code_set: Binary
associated with the Target port
vendor specific: 08 03
Designation descriptor number 3, descriptor length: 20
designator_type: NAA, code_set: Binary
associated with the Addressed logical unit
NAA 6, IEEE Company_id: 0x60e8
Vendor Specific Identifier: 0x7c35000
Vendor Specific Identifier Extension: 0x30c35000002025
[0x60060e8007c350000030c35000002025]
The current code would use the first descriptor because it's longer than
the NAA descriptor. But this is wrong, the kernel is supposed to prefer NAA
descriptors over T10 vendor ID. Designator length should only be used to
compare designators of the same type.
This patch addresses the issue by separating designator priority and
length.

PCI helper functions such as pci_enable/disable_device(),

legacy framework to perform standard operations related to PCI PM.
This driver is using the generic framework and thus calls for those
functions should be dropped as those tasks are now performed by the PCI
core.

Whenever we encounter a sense code of ALUA transitioning in
scsi_io_completion() it means that the SCSI midlayer ran out of retries
trying to wait for ALUA transitioning. In these cases we should be passing
up the error, but signalling that the I/O might be retried, preferably on
another path. So return BLK_STS_AGAIN in these cases.

We should be setting the 'transitioning' ALUA state once we get a Unit
Attention indicating the array is in transitioning. There are arrays which
cannot respond to an RTPG while in transitioning, and others have issues
correctly reporting the state. So better to set the state during Unit
Attention handling and wait for TUR / RTPG to run its course.

When the ALUA state indicates transitioning we should not retry the command
immediately, but rather complete the command with BLK_STS_AGAIN to signal
the completion handler that it might be retried. This allows multipathing
to redirect the command to another path if possible, and avoid stalls
during lengthy transitioning times.

It is simpler for drivers to provide a ->device_reset() callback
irrespective of whether the GPIO, or firmware interface necessary to do the
reset, is discovered during probe.
Change ->device_reset() to return an error code. Drivers that provide the
callback, but do not do the reset operation should return -EOPNOTSUPP.

DeepSleep is a UFS v3.1 feature that achieves the lowest power consumption
of the device, apart from power off.
In DeepSleep mode, no commands are accepted, and the only way to exit is
using a hardware reset or power cycle.
This patch assumes that if a power cycle was an option, then power off
would be preferable, so only exit via a hardware reset is supported.
Drivers that wish to support DeepSleep need to set a new capability flag
UFSHCD_CAP_DEEPSLEEP and provide a hardware reset via the existing
->device_reset() callback.
It is assumed that UFS devices with wspecversion >= 0x310 support
DeepSleep.

A use-after-free or null-pointer error occurs when the 251-byte response
data is copied from IOMB buffer to response message buffer in function
pm8001_mpi_get_nvmd_resp().
After sending the command get_nvmd_data(), the caller begins to sleep by
calling wait_for_complete() and waits for the wake-up from calling
complete() in pm8001_mpi_get_nvmd_resp(). Due to unexpected events (e.g.,
interrupt), if response buffer gets freed before memcpy(), a use-after-free
error will occur. To fix this, the complete() should be called after
memcpy().

In function check_fw_ready() we busy wait using udelay. The CPU is not
released and we see need_resched failures.
Busy waiting is not necessary since we are in process context and we can
sleep instead. Replace udelay with msleep of 20 ms intervals while waiting
for firmware to become ready.
It has been verified that check_fw_ready is not being used in interrupt
context anywhere, hence it is safe to make this change.

Incorrect value of the running_req was causing the driver unload to be
stuck during the SAS lldd_dev_gone notification handling. During SATA I/O
completion, for some error status values, the driver schedules the event
handler and running_req is decremented from that. However, there are some
other error status values (like IO_DS_IN_RECOVERY,
IO_XFER_ERR_LAST_PIO_DATAIN_CRC_ERR) where the I/O has already been
completed by fw/driver so running_req is not decremented.
Also during NCQ error handling, driver itself will initiate READ_LOG_EXT
and ABORT_ALL. When libsas/libata initiate READ_LOG_EXT (0x2F), driver
increments running_req. This will be completed by the driver in
pm80xx_chip_sata_req(), but running_req was not decremented.

Driver submits all internal requests (like abort_task, event acknowledgment
etc.) through inbound queue 0. While submitting those, driver does not
acquire any lock and this may lead to a race when there is an I/O request
coming in on CPU0 and submitted through inbound queue 0. To avoid this,
lock acquisition has been moved to pm8001_mpi_build_cmd(). All command
submission will go through this path.
