Subject: [linux-next:master 5819/9634] drivers/firmware/smccc/kvm_guest.c:89:32: error: invalid application of 'sizeof' to an incomplete type 'struct target_impl_cpu'
Date: Sat, 8 Mar 2025 15:42:57 +0800 [thread overview]
Message-ID: <202503081522.IB63qRPZ-lkp@intel.com> (raw)
tree: https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
head: 0a2f889128969dab41861b6e40111aa03dc57014
commit: 86edf6bdcf0571c07103b8751e9d792a4b808e97 [5819/9634] smccc/kvm_guest: Enable errata based on implementation CPUs
config: arm-defconfig (https://download.01.org/0day-ci/archive/20250308/202503081522.IB63qRPZ-lkp@intel.com/config)
compiler: clang version 21.0.0git (https://github.com/llvm/llvm-project e15545cad8297ec7555f26e5ae74a9f0511203e7)
reproduce (this is a W=1 build): (https://download.01.org/0day-ci/archive/20250308/202503081522.IB63qRPZ-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/202503081522.IB63qRPZ-lkp@intel.com/
Note: the linux-next/master HEAD 0a2f889128969dab41861b6e40111aa03dc57014 builds fine.
It may have been fixed somewhere.
