Subject: [PATCH 1/2] kconfig: narrow the scope of variables in the lexer
Date: Mon, 27 Sep 2021 21:54:36 +0900 [thread overview]
Message-ID: <20210927125437.818092-1-masahiroy@kernel.org> (raw)
The variables, "ts" and "i", are used locally in the action of
the [ \t]+ pattern in the <HELP> start state.
Define them where they are used.
