[0/7] mpt3sas: Enhancements and bug fixes

Message

This patch set has below bug fixes and enhancements.

Dump IOC system interface register set when IOC fails to
transit to READY state during initialization.

During controller reset, cancel the running work along
with the queued works. This avoids processing the expired event after
the controller reset.

Before returning the target/lun reset with failure status
to SML, poll all the reply descriptor pools looking for the reply of
timed out SCSI command. Due to interrupt latency issues it is possible
that interrupt for timed out command might have been delayed. So poll
all the reply descriptor pools looking for the reply of timed out SCSI
command, if the timed out command 's reply is found then return
success status other return failure status.

Memset the config command reply buffer before issuing the
config request.

  mpt3sas: Added support functions to find target and luns.
  mpt3sas: Postprocessing of target and LUN reset.

Suganath,

Applied to my staging tree. You'll get a formal merge message once 5.10
opens.

A few asks for the next submission:

 - Please revisit Documentation/process/submitting-patches.rst section 2
   about how to write commit messages.

 - Please don't include outbox driver files in the submitted patches.

 - Please build with C=1/W=1. Lots of warnings in this code.
