If module initialization fails after the character device has been
registered, unregister the character device. Additionally, avoid
duplicating error path code.

Make qla2x00_process_response_queue() easier to read by splitting this
function. This patch does not change any functionality.

Make the code easier to read by avoiding to use a hard-coded constant. This

Make qla2x00_get_host_fabric_name() slightly faster by changing a stack
array into a static array. Declare that array const now that the
wwn_to_u64() argument pointer has been declared const.

This patch converts driver wait time from using msleep to
wair_event_timeout to prevent race condition.

This patch allows driver to unload using "modprobe -r" when FC-NVMe LUNs
are connected.

Add mutex protection to prevent driver from freeing the FW dump buffer
while the extraction is in progress.

If fw dump buffer size changes and there is an existing fw dump, then save
the old dump in the newly allocated buffer.

Recent ISPs have larger and more complex flash-write semantics
(secure-access and signing). The BSG interfaces support these semantics for
all ISPs and is exclusively used by QLogic user-space tools. Limit
flash-write operations to ISPs <= 25xx.

Commit e6f77540c067 ("scsi: qla2xxx: Fix an integer overflow in sysfs
code") incorrectly set 'optrom_region_size' to 'start+size', which can
overflow option-rom boundaries when 'start' is non-zero. Continue setting
optrom_region_size to the proper adjusted value of 'size'.

With FC-NVMe enabled, driver does not support T10 DIF/DIX. This patch
disables T10-PI information when ql2xnvmeenable is set.

This patch increases max_sgl_segments from 128 to the maximum supported
which is 1024. Increasing max_sgl_segments allows the driver to support
larger I/O sizes.

Driver maintains state machine for processing and completing switch
commands. This patch resets FCF_ASYNC_{SENT|ACTIVE} flag to indicate if the
previous command is active or sent, in order for next GPSC command to
advance the state machine.

This patch sets QPair pointer to NULL to prevent abort command racing ahead
of normal command completion handling during scsi_done call.

This patch tries to address race condition between abort handler and
completion handler. When scsi command result is set by both abort and
completion handler, scsi_done() is only called after refcount on SRB
structure goes to zero. The abort handler sets this result prematurely even
when the refcount is non-zero value. Fix this by setting SCSI cmd->result
before scsi_done() is called.

Clang warns when it sees a logical not on the left side of a conditional
statement because it thinks the logical not should be applied to the whole
statement, not just the left side:
drivers/scsi/qla2xxx/qla_nx.c:3703:7: warning: logical not is only
applied to the left hand side of this comparison
[-Wlogical-not-parentheses]
This particular instance was already fixed by commit 0bfe7d3cae58 ("scsi:
qla2xxx: Simplify conditional check") upstream but it was reintroduced by
commit 3695310e37b4 ("scsi: qla2xxx: Update flash read/write routine") in
the 5.2/scsi-queue.

Includes the following:
- correction to 27xx image status struct;
- factoring of 27xx image status validating routines to make common;
- image status generation compare that works across zero wrap;
- bsg interface to report current active images (as loaded by driver).
