6a965ee189 scsi: mpt3sas: Suppress a warning in debug kernel
The mpt3sas_ctl_exit() should be called after communication with the
controller stops but currently it may cause false warnings about not
released memory. Fix this by letting mpt3sas_ctl_exit() handle misc driver
release per driver and release DMA in mpt3sas_ctl_release() per ioc.

e188215562 scsi: mpt3sas: Replace dynamic allocations with local variables
mpt3sas_scsih.c:_scsih_scan_for_devices_after_reset() allocates and fetches
a MPI2_CONFIG_PAGE_RAID_VOL_0 struct (Mpi2RaidVolPage0_t) and a
MPI2_CONFIG_PAGE_RAID_VOL_1 struct (Mpi2RaidVolPage1_t), but does not
include the terminal flexible array members in the struct size
calculations, fetch those members, or otherwise use those members in any
way.

These dynamic allocations can be replaced with local variables.

66f2a53fc6 scsi: mpt3sas: Remove the iounit_pg8 member of the per-adapter struct
The per-adapter struct (struct MPT3SAS_ADAPTER) contains a
MPI2_CONFIG_PAGE_IO_UNIT_8 (Mpi2IOUnitPage8_t) iounit_pg8 member that is
populated by mpt3sas_base.c:_base_static_config_pages().

As the name of that function indicates, the iounit_pg8 member represents a
static configuration page data structure that rarely changes, and is among
several such static config pages that are currently being fetched once per
adapter per init (or reset) and copied to the per-adapter struct for later
use.

However, unlike the other static config pages, the iounit_pg8 member is
never actually used outside of _base_static_config_pages(). Also,
Mpi2IOUnitPage8_t has a flexible array member, making its presence in the
_middle_ of the per-adapter struct rather strange.

Remove this member from the per-adapter struct and fix up the portion of
_base_static_config_pages() that uses it.

f7830af68e scsi: mpt3sas: Make MPI2_CONFIG_PAGE_IO_UNIT_8::Sensor[] a flexible array
This terminal 1-length variable array can be directly converted into a C99
flexible array member.

As all users of MPI2_CONFIG_PAGE_IO_UNIT_8 (Mpi2IOUnitPage8_t) do not use
Sensor[], no further source changes are required to accommodate its reduced
sizeof():

 - mpt3sas_config.c:mpt3sas_config_get_iounit_pg8() fetches a
   Mpi2IOUnitPage8_t into a caller-provided buffer, assuming
   sizeof(Mpi2IOUnitPage8_t) as the buffer size. It has one caller:

   - mpt3sas_base.c:_base_static_config_pages() passes the address of the
     Mpi2IOUnitPage8_t iounit_pg8 member of the per-adapter struct (struct
     MPT3SAS_ADAPTER *ioc) as the buffer. The assumed buffer size is
     therefore correct.

     However, the only subsequent use in mpt3sas of the thus populated
     ioc->iounit_pg8 is a little further on in the same function, and this
     use does not involve ioc->iounit_pg8.Sensor[].

     Note that iounit_pg8 occurs in the middle of the per-adapter struct,
     not at the end. The per-adapter struct is extensively used throughout
     mpt3sas even if its iounit_pg8 member isn't, resulting in an
     especially large amount of noise when comparing binary changes
     attributable to this commit.

These terminal 1-length variable arrays can be directly converted into C99

In most cases, they belong to unused structs, or to structs used only by

in roundabout ways that do not depend on the sizeof() their structs.

The driver retries certain register reads 3 times if the returned value is
0. This was done because the controller could return 0 for certain
registers if other registers were being accessed concurrently by the BMC.

In certain systems with increased BMC interactions, the register values
returned can be 0 for longer than 3 retries. Change the retry count from 3
to 30 for the affected registers to prevent problems with out-of-band

Messages.  Since commit f26e58bf6f ("PCI/AER: Enable error reporting when
AER is native"), the PCI core does this for all devices during enumeration,
so the driver doesn't need to do it itself.

Remove the redundant pci_enable_pcie_error_reporting() call from the
driver.  Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.

Note that this only controls ERR_* Messages from the device.  An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

d3c57724f1 scsi: mpt3sas: Fix NULL pointer access in mpt3sas_transport_port_add()
Port is allocated by sas_port_alloc_num() and rphy is allocated by either
sas_end_device_alloc() or sas_expander_alloc(), all of which may return
NULL. So we need to check the rphy to avoid possible NULL pointer access.

If sas_rphy_add() returned with failure, rphy is set to NULL. We would
access the rphy in the following lines which would also result NULL pointer
access.

change their return type into void. Most callers ignore the returned value

746fc76b82 SCSI misc on 20220804
Updates to the usual drivers (ufs, qla2xx, target, lpfc, smartpqi,
 mpi3mr).  The main driver change that might cause issues on down the
 road is the conversion of some of our oldest surviving drivers to the
 DMA API (should only affect m68k).  The only major core change is the
 rework of async resume; the rest are either completely trivial or for
 updating deprecated APIs.

0fde22c542 scsi: mpt3sas: Stop fw fault watchdog work item during system shutdown
During system shutdown or reboot, mpt3sas will reset the firmware back to
ready state. However, the driver leaves running a watchdog work item
intended to keep the firmware in operational state. This causes a second,
unneeded reset on shutdown and moves the firmware back to operational
instead of in ready state as intended. And if the mpt3sas_fwfault_debug
module parameter is set, this extra reset also panics the system.

mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the
firmware back to ready state.
