Subject: [PATCH 08/29] modpost: remove get_next_text() and make {grab,release_}file static
Date: Sun, 17 May 2020 18:48:38 +0900 [thread overview]
Message-ID: <20200517094859.2376211-9-masahiroy@kernel.org> (raw)
In-Reply-To: <20200517094859.2376211-1-masahiroy@kernel.org>
get_next_line() is no longer used. Remove.
grab_file() and release_file() are only used in modpost.c. Make them
static.
