Subject: [PATCH V2 2/6] mmc: sh_mobile_sdhi: remove obsolete irq_by_name registration
Date: Tue, 26 Apr 2016 17:55:23 +0200 [thread overview]
Message-ID: <1461686127-3217-3-git-send-email-wsa@the-dreams.de> (raw)
In-Reply-To: <1461686127-3217-1-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.
