Subject: [PATCH] MIPS: launch.h: add include guard to prevent build errors
Date: Thu, 20 May 2021 22:13:43 -0700 [thread overview]
Message-ID: <20210521051343.20059-1-rdunlap@infradead.org> (raw)
arch/mips/include/asm/mips-boards/launch.h needs an include guard
to prevent it from being #included more than once.
Prevents these build errors:
In file included from ../arch/mips/mti-malta/malta-amon.c:16:
../arch/mips/include/asm/mips-boards/launch.h:8:8: error: redefinition of 'struct cpulaunch'
8 | struct cpulaunch {
| ^~~~~~~~~

from ../arch/mips/include/asm/smp.h:21,
from ../include/linux/smp.h:114,
from ../arch/mips/mti-malta/malta-amon.c:12:
../arch/mips/include/asm/mips-boards/launch.h:8:8: note: originally defined here
8 | struct cpulaunch {
| ^~~~~~~~~
make[3]: [../scripts/Makefile.build:273: arch/mips/mti-malta/malta-amon.o] Error 1 (ignored)
Fixes: 6decd1aad15f ("MIPS: add support for buggy MT7621S core detection")
