Double lock feature can have the following possible values. 0b0000 - Double lock implemented 0b1111 - Double lock not implemented But in case of a conflict the safe value should be 0b1111. Hence this must be a signed feature instead. Also change FTR_EXACT to FTR_LOWER_SAFE. While here, fix the erroneous bit width value from 28 to 4.

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.
