[SCSI] lpfc 8.3.26: Fix SYSFS interface issues
Fix SYSFS interface issues.
- In the lpfc_sli4_pdev_status_reg_wait() routine, after initial 100ms delay
following write to PHYSDEV_CONTROL register for the firmware reaction, check
the RN bit and ERR bit of the SLIPORT_STATUS register. If none of them
became 1, the previous PHYSDEV_CONTROL register should be considered failed
due to lack of privilege and error for no permission should be returned
immediately without getting into the wait for RDY bits on the SLIPORT_STATUS
register.
- Remove the driver check on dev->is_physfn before proceed to perform the
PHYSDEV_CONTROL register write, and let the PCI function's privilege
setting and driver handling of PHYSDEV_CONTROL register write failure to
handle the reset-ability through the SLI port.
- Added key to ctlreg_write to prevent unauthorized or unexpected write to
the control register.
- Change return to EACCES for sysfs access that are failed because hba_reset
is disabled.
