Call sas_remove_host() before removing the target devices in the driver's .remove() callback function(i.e. during driver unload time). So that driver can provide a way to allow SYNC CACHE, START STOP unit commands etc. (which are issued from SML) to the target drives during driver unload time. Once sas_remove_host() is called before removing the target drives then driver can just clean up the resources allocated for target devices and no need to call sas_port_delete_phy(), sas_port_delete() API's as these API's internally called from sas_remove_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.
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.
