Subject: 8250/fintek: rename IRQ_MODE macro
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=87a713c8ffca33d8e497a8b6c02034332bd80394;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

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

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.
