powerpc/pci: Fix get_phb_number() locking # # The recent change to get_phb_number() causes a DEBUG_ATOMIC_SLEEP # warning on some systems: # # BUG: sleeping function called from invalid context at

# This is because pcibios_alloc_controller() holds hose_spinlock but # of_alias_get_id() takes of_mutex which can sleep. # # The hose_spinlock protects the phb_bitmap, and also the hose_list, but # it doesn't need to be held while get_phb_number() calls the OF routines, # because those are only looking up information in the device tree. # # So fix it by having get_phb_number() take the hose_spinlock itself, only # where required, and then dropping the lock before returning. # pcibios_alloc_controller() then needs to take the lock again before the # list_add() but that's safe, the order of the list is not important. # # Fixes: 0fe1e96fef0a ("powerpc/pci: Prefer PCI domain assignment via DT 'linux,pci-domain' and alias") # Reported-by: Guenter Roeck # Signed-off-by: Michael
