From 0744ea2a01cb75a750e8594b046102fc68fa45b3 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Mon, 23 Feb 2015 12:30:46 +0000 Subject: [PATCH] spi: s3c64xx: fix compiler warning in spi-s3c64xx The Exynos 7 arm64 support now allows the S3C64xx SPI driver to be compiled into an ARM64 kernel, so the cast from the [rt]x_dmach int variable to a void* in this driver now triggers a warning. Add a long cast to silence the compiler.
