Subject: [PATCH] aacraid: stop using deprated get_seconds()
Date:   Mon, 18 Jun 2018 17:26:47 +0200
Message-Id: <20180618152734.1705907-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

get_seconds() can overflow on 32-bit architectures and is deprecated
because of that. The use in the aacraid driver has the same problem due
to a limited firmware interface, it also overflows in the year 2106.

This changes all calls to get_seconds() to the non-deprecated
ktime_get_real_seconds(), which unfortunately doesn't solve that problem
but gets rid of one user of the deprecated interface.
