Hi Liviu Dudau,
When CONFIG_PCI=n, the following build errors happen. :-(
Would you confirm this?
In file included from include/linux/pci.h:1393:0,
from drivers/scsi/scsi_lib.c:19:
arch/arm64/include/asm/pci.h:31:19: error: redefinition of 'pci_domain_nr'
static inline int pci_domain_nr(struct pci_bus *bus)
^
In file included from drivers/scsi/scsi_lib.c:19:0:
include/linux/pci.h:1383:19: note: previous definition of 'pci_domain_nr' was here
static inline int pci_domain_nr(struct pci_bus *bus) { return 0; }
^
.....
Best regards,
Jingoo Han
