When a user-supplied value is out of range, (NEW) and an incorrect default
value are shown.
[Test Kconfig]
config FOO
int "foo"
range 10 20
[Test .config]
CONFIG_FOO=30
[Result without this fix]
$ make config
*
* Main menu
*
foo (FOO) [10] (NEW)
[Result with this fix]
$ make config
*
* Main menu
*
foo (FOO) [20]
Currently, the SYMBOL_DEF_USER is cleared if the user input does not
reside within the range. Kconfig forgets the initial value 30, and
prints (NEW) and an incorrect default [10].
Kconfig should remember the user's input. The default should be [20]
because the user's input, 30, is closer to the upper limit of the range.
Please note it will not show up in "make oldconfig" because it is no
longer considered as a new symbol. It also fixes the inconsistent
behavior in listnewconfig/helpnewconfig.

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.
