Add pm80xx_fatal_error_uevent_emit() which is called when the pm80xx driver encouters a fatal error. The uevent has the following additional custom key/value pair sets: - DRIVER: driver name, pm80xx in this case - HBA_NUM: the scsi host id of the device - EVENT_TYPE: to indicate a fatal error - REPORTED_BY: either driver or firmware The uevent is anchored to the kernel object that represents the SCSI controller, which includes other useful core variables, such as, ACTION, DEVPATH, SUBSYSTEM, and more. The fatal_error_uevent_emit() function is called when the controller fatal error state changes. Since this doesn't happen often for a specific SCSI host, there is no worries of a uevent storm.

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.
