Subject: [4.4-stable 04/22] isdn: sc: work around type mismatch warning
Date: Tue, 20 Feb 2018 12:54:51 +0100	[thread overview]
Message-ID: <20180220115527.1806578-5-arnd@arndb.de> (raw)
In-Reply-To: <20180220115527.1806578-1-arnd@arndb.de>

This driver shows warnings on many architectures:

drivers/isdn/sc/init.c: In function 'identify_board':
drivers/isdn/sc/init.c:484:2: error: passing argument 1 of 'readl' makes pointer from integer without a cast [-Werror]

In newer kernels, it was completely removed, but for the 4.4-stable
series, let's just shut up that warning by adding an extra variable
to do the necessary type cast.
