ASoC: rcar: dma: remove unnecessary "volatile"
commit 2a3af642eb20("ASoC: rcar: clear DE bit only in PDMACHCR...") added rsnd_dmapp_bset(), but it used copy-paste. Thus, it had unnecessary "volatile", and had below warning on x86. This patch fix it. sound/soc/sh/rcar/dma.c: In function 'rsnd_dmapp_bset': >> sound/soc/sh/rcar/dma.c:463:21: warning: passing argument 1 of \ 'ioread32' discards 'volatile' qualifier from pointer target \ type [-Wdiscarded-qualifiers] u32 val = ioread32(addr); ^~~~ In file included from arch/x86/include/asm/io.h:203:0, from arch/x86/include/asm/realmode.h:5, from arch/x86/include/asm/acpi.h:33, from arch/x86/include/asm/fixmap.h:19, from arch/x86/include/asm/apic.h:10, from arch/x86/include/asm/smp.h:12, from include/linux/smp.h:59, from include/linux/topology.h:33, from include/linux/gfp.h:8, from include/linux/idr.h:16, from include/linux/kernfs.h:14, from include/linux/sysfs.h:15, from include/linux/kobject.h:21, from include/linux/of.h:21, from include/linux/of_dma.h:16, from sound/soc/sh/rcar/dma.c:12: include/asm-generic/iomap.h:31:21: note: expected 'void *' \ but argument is of type 'volatile void *' extern unsigned int ioread32(void __iomem *); ^~~~~~~~ Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
