If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann 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.
