Subject: [PATCH 27/37] modpost: remove get_next_text() and make {grab,release_}file static
Date: Mon,  1 Jun 2020 14:57:21 +0900	[thread overview]
Message-ID: <20200601055731.3006266-27-masahiroy@kernel.org> (raw)
In-Reply-To: <20200601055731.3006266-1-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.
