[ Upstream commit 3ada501d602abf02353445c03bb3258146445d90 ] Avoid dropping into shell if the controller is in locked up state. Driver issues SIS soft reset to bring back the controller to SIS mode while OS boots into kdump mode. If the controller is in lockup state, SIS soft reset does not work. Since the controller lockup code has not been cleared, driver considers the firmware is no longer up and running. Driver returns back an error code to OS and the kdump fails.

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.
