Subject: [PATCH 2/6] mmc: sh_mobile_sdhi: remove obsolete irq_by_name registration
Date: Wed, 06 Apr 2016 09:25:30 +0000	[thread overview]
Message-ID: <1459934734-3613-3-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1459934734-3613-1-git-send-email-wsa@the-dreams.de>

From: Wolfram Sang <wsa+renesas@sang-engineering.com>

There is no user left in the kernel, so this code can be removed.
(Legacy, non-DT sh_mobile boards have been removed a while ago.) The
diff looks more complicated than it is: The if-block for multiplexed isr
is now the main code path, the rest is removed. A number of sh boards
included the now deleted include file without needing it. Remove that,
too.
