This commit decreases 6 shift/reduce conflicts, and finally achieves
conflict-free parser.
Since Kconfig has no terminator for a config block, detecting the end
of config_stmt is not easy.
For example, there are two ways for handling the error in the following
code:
1 config FOO
2 =
[A] Print "unknown option" error, assuming the line 2 is a part of
config_option_list
[B] Print "invalid statement", assuming the line 1 is reduced into
a config_stmt by itself
Bison actually chooses [A] because it performs the shift rather than
the reduction where both are possible.
However, there is no reason to choose one over the other.
Let's remove the option_error, and let it fall back to [B].

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.
