Subject: [PATCH 4/4] sh: remove board_time_init() callback
Date:   Fri, 20 Apr 2018 17:48:56 +0200
Message-Id: <20180420154933.3235131-4-arnd@arndb.de>
In-Reply-To: <20180420154933.3235131-1-arnd@arndb.de>
References: <20180420154933.3235131-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The only remaining user of board_time_init() is the of-generic
machine, and that just calls the global timer_init() function.
Calling that one has no effect on non-DT platforms, so we can
simply call it unconditionally in place of board_time_init().
