MIPS: launch.h: add include guard to prevent build errors
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 { | ^~~~~~~~~ In file included from ../arch/mips/include/asm/mips-cps.h:13, from ../arch/mips/include/asm/smp-ops.h:16, 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") Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kernel test robot <lkp@intel.com> Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Cc: linux-mips@vger.kernel.org Cc: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com> Reviewed-by: Ilya Lipnitskiy <ilya.lipnitskiy@gmail.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
