Subject: [PATCH v3 17/17] ARM: drop old LoCoMo driver
Date: Sun, 17 May 2015 19:27:57 +0300	[thread overview]
Message-ID: <1431880077-26321-18-git-send-email-dbaryshkov@gmail.com> (raw)
In-Reply-To: <1431880077-26321-1-git-send-email-dbaryshkov-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

As there are no in-kernel users of old locomo driver, drop all
alltogether. Remove Kconfig entry, driver and header.
