The dme_peer get/set attribute commands are prone to errors, therefore
we add three retries for the UIC command sending. Error code returned
from ufshcd_send_uic_cmd() is checked, and unless it was successful or
the retries have finished, another command will be sent.

If device raises the exception event in the response to the commands
sent during the runtime/system PM callbacks, exception event handler
might run in parallel with PM callbacks and may see unclocked register
accesses. This change fixes this issue by not scheduling the exception
event handler while PM callbacks are running.

fDeviceInit query response time for some devices is too long that
default query request timeout of 100ms may not be enough. Experiments
show that fDeviceInit response sometimes takes 500ms so to be on safer
side this change sets the timeout to 600ms. Without this change, we
might unnecessarily have to retry fDeviceInit query requests multiple
times and each query request timeout prints one error message.

When sending a query to the device returns with a timeout error, we

A race condition appear to exist between request completion when
scsi_done() is called to end the request and set the tag back to -1 (at
blk_queue_end_tag() scsi_end_request), and scsi layer error handling
which aborts the command and reuses it to request sense data. Sending
the request sense is done with tag which was set to -1 and so it is
invalid. Assert command tag passed from scsi layer is valid.

Some of the data structures (like response UPIU) and/or its elements
(unused fields) should be cleared before sending out the respective
command to UFS device.
This change clears the UPIU response data structure for query commands
and NOP command before sending out the command. We also initialize the
PRDT table length to zero which should take care of commands which
doesn't have any data associated with it. We are also clearing the
unused fields in request UPIU for NOP command.

Clear the UFS data structures before sending new request.
The SCSI command is sent to the device within the UFS UPIU request.
As part of the transfer UPIU preparation, the SCSI command is copied
to the UPIU structure according to the SCSI command size.
As different SCSI commands differ in size from each other, we need
to clear the whole SCSI command field to prevent sending uninitialized
data to the device.
The UPIU response doesn't always include the sense data and can differ
in size.
Hence, the UPIU response should also be cleared before the transfer.

When the scsi_dh core was moved into the scsi core module,
CONFIG_SCSI_DH became a 'bool' option, and now anything depending on it
can be built-in even when CONFIG_SCSI=m. This of course cannot link
successfully:
drivers/scsi/built-in.o: In function `rdac_init':
scsi_dh_alua.c:(.init.text+0x14): undefined reference to `scsi_register_device_handler'
scsi_dh_alua.c:(.init.text+0x64): undefined reference to `scsi_unregister_device_handler'
drivers/scsi/built-in.o: In function `alua_init':
scsi_dh_alua.c:(.init.text+0xb0): undefined reference to `scsi_register_device_handler'
As a workaround, this adds an extra dependency on CONFIG_SCSI, so
Kconfig can figure out whether built-in is allowed or not.

Unfortunately, I don't see any helpful way to add proper error handling

while driver removal is in progress or PCI shutdown is invoked, driver
kills AIF aacraid thread, but IOCTL requests from the management tools
re-start AIF thread leading to IOP_RESET.
Fixed by setting adapter_shutdown flag when PCI shutdown is invoked.

aac_mutex was used to create protect the ioctl path for only the compat
path, it would be make more sense to place mutex in aac_do_ioctl, which
is the main ioctl function call that handles all ioctl commands.
Created new mutex ioctl_mutex in struct aac_dev to protect switch case
in aac_do_ioctl and removed aac_mutex from aac_cfg_ioctl and
aac_compat_do_ioctl
