So this *again* has absolutely nothing to do with the:
"platform/x86: thinkpad_acpi: Fix bitwise vs. logical warning"
commit, the problem is that:
1. the .config does not have CONFIG_PCI set; combined with:
2. include/pci.h using a #define instead of a
static inline for pci_dev_present() when this is the case
3. This is a clang WERROR build
I'll submit a fix for 2. upstream which should also fix
similar errors in a lot of other drivers.
Again I must say that as a maintainer I'm unhappy about the amount
of noise being generated by clang WERROR builds here though,
is it really necessary for the kernel test robot to do builds
of this type ?

Hans
