Qianfeng Rong 5cffc679ad scsi: lpfc: Use int type to store negative error codes
Change the 'ret' variable in lpfc_sli4_issue_wqe() from uint32_t to int,
as it needs to store either negative error codes or zero returned by
lpfc_sli4_wq_put().

Storing the negative error codes in unsigned type, doesn't cause an
issue at runtime but can be confusing.  Additionally, assigning negative
error codes to unsigned type may trigger a GCC warning when the
-Wsign-conversion flag is enabled.

No effect on runtime.

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 reStructuredText 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.
