arm64: Provide a namespace to NCAPS
commit 06f9eb884be81431d54d7d37390043e3b5b7f14a upstream Building arm64.allmodconfig leads to the following warning: usb/gadget/function/f_ncm.c:203:0: warning: "NCAPS" redefined #define NCAPS (USB_CDC_NCM_NCAP_ETH_FILTER | USB_CDC_NCM_NCAP_CRC_MODE) ^ In file included from /home/build/work/batch/arch/arm64/include/asm/io.h:32:0, from /home/build/work/batch/include/linux/clocksource.h:19, from /home/build/work/batch/include/clocksource/arm_arch_timer.h:19, from /home/build/work/batch/arch/arm64/include/asm/arch_timer.h:27, from /home/build/work/batch/arch/arm64/include/asm/timex.h:19, from /home/build/work/batch/include/linux/timex.h:65, from /home/build/work/batch/include/linux/sched.h:19, from /home/build/work/batch/arch/arm64/include/asm/compat.h:25, from /home/build/work/batch/arch/arm64/include/asm/stat.h:23, from /home/build/work/batch/include/linux/stat.h:5, from /home/build/work/batch/include/linux/module.h:10, from /home/build/work/batch/drivers/usb/gadget/function/f_ncm.c:19: arch/arm64/include/asm/cpufeature.h:27:0: note: this is the location of the previous definition #define NCAPS 2 So add a ARM64 prefix to avoid such problem.
