Subject: [PATCH 07/27] kconfig: clean up EOF handling in the lexer
Date:   Tue, 11 Dec 2018 20:00:50 +0900
Message-Id: <1544526070-16690-8-git-send-email-yamada.masahiro@socionext.com>
In-Reply-To: <1544526070-16690-1-git-send-email-yamada.masahiro@socionext.com>
References: <1544526070-16690-1-git-send-email-yamada.masahiro@socionext.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

A new file should always start in the INITIAL state.

When the lexer bumps into EOF, the lexer must get back to the INITIAL
state anyway. Remove the redundant <<EOF>> pattern in the PARAM state.
