When we know we will reassign all resources, trying (and failing) to allocate them initially is fairly pointless and leads to a lot of scary messages in the kernel log Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> -- This one probably needs testing on a few platforms but I think it's correct ;-) --- arch/powerpc/kernel/pci-common.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-)
