[PATCH v2 0/6] mpt3sas: Improve device readiness handling and event recovery

[Ranjan Kumar <ranjan.kumar@broadcom.com>]

This patch series enhances the mpt3sas driver’s device bring-up,
readiness detection, and event recovery mechanisms to improve
robustness in environments with slow-responding or transient
SAS/PCIe devices.

The series introduces optional control over issuing TEST UNIT READY
(TUR) commands during device unblocking, configurable retry limits,
and a mechanism to requeue firmware topology events when devices are
temporarily busy. Together, these updates reduce discovery failures
and improve recovery reliability following firmware or link events.

Change since v1:
- Fixed test robot build warnings
- Fixed W=1 compilation warnings

  mpt3sas: Added no_turs flag to device unblock logic
  mpt3sas: Added issue_scsi_cmd_to_bringup_drive module parameter part-1
  mpt3sas: improve device discovery and readiness handling for slow
    devices part-2
  mpt3sas: Add firmware event requeue support for busy devices
  mpt3sas: Add configurable command retry limit for slow-to-respond
    devices
  mpt3sas: Fixed the W=1 compilation warning
