[PATCH 07/27] kconfig: clean up EOF handling in the lexer

From: Masahiro Yamada
Date: Tue Dec 11 2018 - 06:04:14 EST


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.
