[ Upstream commit d35f7672715d1ff3e3ad9bb4ae6ac6cb484200fe ] During initialization, the driver allocates wq->pring in lpfc_wq_create and lpfc_sli4_queue_unset() is the only place where kfree(wq->pring) is called. There is a possible memory leak in lpfc_sli_brdrestart_s4() (restart) and lpfc_pci_remove_one_s4() (rmmod) paths because there are no calls to lpfc_sli4_queue_unset() to kfree() the wq->pring. Fix by inserting a call to lpfc_sli4_queue_unset() in lpfc_sli_brdrestart_s4() and lpfc_sli4_hba_unset() routines. Also, add a check for the SLI_ACTIVE flag before issuing the Q_DESTROY mailbox command. If not set, then the mailbox command will obviously fail. In such cases, skip issuing the mailbox command and only execute the driver resource clean up portions of the lpfc_*q_destroy routines.

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.
