This patch fixes below Smatch reported issues:
1. lpfc_hbadisc.c:3020 lpfc_mbx_cmpl_fcf_rr_read_fcf_rec()
error: uninitialized symbol 'vlan_id'.
2. lpfc_hbadisc.c:3121 lpfc_mbx_cmpl_read_fcf_rec()
error: uninitialized symbol 'vlan_id'.
3. lpfc_init.c:335 lpfc_dump_wakeup_param_cmpl()
warn: always true condition '(prg->dist < 4) => (0-3 < 4)'
4. lpfc_init.c:2419 lpfc_parse_vpd()
warn: inconsistent indenting.
5. lpfc_init.c:13248 lpfc_sli4_enable_msi()
warn: 'phba->pcidev->irq' 2147483648 can't fit into 65535
'eqhdl->irq'
6. lpfc_debugfs.c:5300 lpfc_idiag_extacc_avail_get()
error: uninitialized symbol 'ext_cnt'
7. lpfc_debugfs.c:5300 lpfc_idiag_extacc_avail_get()
error: uninitialized symbol 'ext_size'
8. lpfc_vmid.c:248 lpfc_vmid_get_appid()
warn: sleeping in atomic context.
9. lpfc_init.c:8342 lpfc_sli4_driver_resource_setup()
warn: missing error code 'rc'.
10. lpfc_init.c:13573 lpfc_sli4_hba_unset()
warn: variable dereferenced before check 'phba->pport' (see
line 13546)
11. lpfc_auth.c:1923 lpfc_auth_handle_dhchap_reply()
error: double free of 'hash_value'
Fixes:
1. Initialize vlan_id to LPFC_FCOE_NULL_VID.
2. Initialize vlan_id to LPFC_FCOE_NULL_VID.
3. prg->dist is a 2 bit field. Its value can only be between 0-3.
Remove redundent check 'if (prg->dist < 4)'.
4. Fix inconsistent indenting. Moved logic into helper function
lpfc_fill_vpd().
5. Define 'eqhdl->irq' as int value as pci_irq_vector() returns int.
Also, check for return value of pci_irq_vector() and log message in
case of failure.
6. Initialize 'ext_cnt' to 0.
7. Initialize 'ext_size' to 0.
8. Use alloc_percpu_gfp() with GFP_ATOMIC flag.
9. 'rc' was not updated when dma_pool_create() fails. Update 'rc =
-ENOMEM' when dma_pool_create() fails before calling goto statement.
10. Add check for 'phba->pport' in lpfc_cpuhp_remove().
11. Initialize 'hash_value' to NULL, same like 'aug_chal' variable.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
