783e0dc4f6 qla2xxx: Check for device state before unloading the driver.
During hot swap of PCI device, there can be PCI error on device,
during normal driver unload. The race between normal driver unload and
driver unload due to PCI error, can lead to system crash.Fix is to check
if there is unload going on and allow that function to unload the driver.

ef8d1d51aa qla2xxx: setup data needed in ISR before setting up the ISR
qla2xxx first calls request_irq() and then does the setup of the queue
entry data needed in the interrupt handlers in when using MSI-X. This
could lead to a NULL pointer dereference when an IRQ fires between the
request_irq() call and the assignment of the qentry data structure to
the rsp->msix field. A possible case for such a race would be in the
kdump case when the HBA's IRQs are still enabled but the driver is
undergoing a new initialisation and thus is not aware of already
activated IRQs in the HBA.

5ea33eb573 qla2xxx: Remove use of 'struct timeval'
struct register_host_info stores a 64-bit UTC system time timestamp.
This patch removes the use of 'struct timeval' to obtain that timestamp
as its tv_sec value will overflow on 32-bit systems in year 2038 beyond.
The patch uses ktime_get_real_seconds() which returns a 64-bit seconds value.

bc7095a926 qla2xxx: avoid maybe_uninitialized warning
The qlt_check_reserve_free_req() function produces an incorrect warning
when CONFIG_PROFILE_ANNOTATED_BRANCHES is set:

drivers/scsi/qla2xxx/qla_target.c: In function 'qlt_check_reserve_free_req':

drivers/scsi/qla2xxx/qla_target.c:1887:3: error: 'cnt' may be used uninitialized in this function [-Werror=maybe-uninitialized]

The problem is that gcc fails to track the state of the condition across
an annotated branch.

This slightly rearranges the code to move the second if() block
into the first one, to avoid the warning while retaining the
behavior of the code.

Commit 84e32a0 ("qla2xxx: Use pci_enable_msix_range() instead of
pci_enable_msix()") introduced a regression when target mode is enabled.
In qla24xx_enable_msix(), ha->max_rsp_queues was incorrectly set
to a value higher than the number of response queues allocated causing
an invalid dereference. Specifically here in qla2x00_init_rings():
    *rsp->in_ptr = 0;
