Bart Van Assche a60a3523b3 scsi: core: scsi_get_device_flags_keyed(): Always return device flags 
[ Upstream commit a44c9d3650 ]

Since scsi_get_device_flags_keyed() callers do not check whether or not
the returned value is an error code, change that function such that it
returns a flags value even if the 'key' argument is invalid.  Note:
since commit 28a0bc4120 ("scsi: sd: Implement blacklist option for
WRITE SAME w/ UNMAP") bit 31 is a valid device information flag so
checking whether bit 31 is set in the return value is not sufficient to
tell the difference between an error code and a flags value.

README 

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.
