When a SCSI host is registered, the SCSI mid-layer takes a reference to a module in Scsi_host.hostt.module. In doing this, we are prevented from removing the driver module for the host in dangerous scenario, like when a disk is mounted. Currently there is only one scsi_host_template (sht) for all HW versions, and this is the main.c module. So this means that we can possibly remove the HW module in this dangerous scenario, as SCSI mid-layer is only referencing the main.c module. To fix this, create a sht per module, referencing that same module to create the Scsi host.

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.
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.
