From 87a713c8ffca33d8e497a8b6c02034332bd80394 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 10 Aug 2016 23:54:13 +0200 Subject: [PATCH] 8250/fintek: rename IRQ_MODE macro A bugfix for the fintek driver required defining some macros, but one of them clashes with a system header on ARM: drivers/tty/serial/8250/8250_fintek.c:34:0: error: "IRQ_MODE" redefined [-Werror] #define IRQ_MODE 0x70 In file included from /git/arm-soc/arch/arm/include/asm/ptrace.h:13:0, from /git/arm-soc/arch/arm/include/asm/irqflags.h:6, from /git/arm-soc/include/linux/irqflags.h:15, from /git/arm-soc/arch/arm/include/asm/bitops.h:27, from /git/arm-soc/include/linux/bitops.h:36, from /git/arm-soc/include/linux/kernel.h:10, from /git/arm-soc/include/linux/list.h:8, from /git/arm-soc/include/linux/module.h:9, from /git/arm-soc/drivers/tty/serial/8250/8250_fintek.c:11: arch/arm/include/uapi/asm/ptrace.h:55:0: note: this is the location of the previous definition This renames the newly introduced 'IRQ_MODE' macro to FINTEK_IRQ_MODE.
