IOCTLs causing firmware fault may end up in failed controller resets and finally killing the adapter. This patch fixes this problem as stated below: In OCR sequence, driver will attempt refiring pended IOCTLs upto two times. If first two attempts fail, then in third attempt driver will return pended IOCTLs with EBUSY status to application. These changes are done to ensure if any of pended IOCTLs is causing firmware fault and resulting into OCR failure, then in last attempt of OCR driver will refrain firing it to firmware and saving adapter from being killed due to faulty IOCTL.

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.
