Guilherme G. Piccoli 7c9fdfb700 scsi: lpfc: Avoid NULL pointer dereference in lpfc_els_abort()
We might have a NULL pring in lpfc_els_abort(), for example on error
recovery path, since queues are destroyed during error recovery
mechanism.

In this case, we should just drop the abort since the queues will be
recreated anyway. This patch just verifies for NULL pointer and stop the
abortion of the queue in case of a NULL pring.

Also, this patch converts return type of lpfc_els_abort() from int to
void, since it's not checked anywhere.

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
