commit 81b6c999897919d5a16fedc018fe375dbab091c5 upstream.
As it turned out device_get() doesn't use kref_get_unless_zero(), so we
will be always getting a device pointer. Consequently, we need to check
for the device state in __scsi_remove_target() to avoid tripping over
deleted objects.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
