Subject: [linux-next:master 9077/11156] drivers/leds/leds-gpio-register.c:23:32: error: redefinition of 'gpio_led_register_device'
Date: Fri, 1 Mar 2024 10:46:31 +0800 [thread overview]
Message-ID: <202403011013.7cDG1rwi-lkp@intel.com> (raw)
Hi Duje,
First bad commit (maybe != root cause):
tree: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head: f303a3e2bcfba900efb5aee55236d17030e9f882
commit: 7a28f9cf6b7c8cad760b4d4ee7f53231cd76d8e4 [9077/11156] Revert "leds: Only descend into leds directory when CONFIG_NEW_LEDS is set"
config: mips-bcm47xx_defconfig (https://download.01.org/0day-ci/archive/20240301/202403011013.7cDG1rwi-lkp@intel.com/config)
compiler: clang version 15.0.7 (https://github.com/llvm/llvm-project.git 8dfdcc7b7bf66834a761bd8de445840ef68e4d1a)
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20240301/202403011013.7cDG1rwi-lkp@intel.com/reproduce)
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <lkp@intel.com>
| Closes: https://lore.kernel.org/oe-kbuild-all/202403011013.7cDG1rwi-lkp@intel.com/
Note: the linux-next/master HEAD f303a3e2bcfba900efb5aee55236d17030e9f882 builds fine.
It may have been fixed somewhere.
