From: Arnd Bergmann <arnd@xxxxxxxx>
The newly added pci-epf-ntb driver uses configfs, which
causes a link failure when that is disabled at compile-time:
arm-linux-gnueabi-ld: drivers/pci/endpoint/functions/pci-epf-ntb.o: in function `epf_ntb_add_cfs':
pci-epf-ntb.c:(.text+0x954): undefined reference to `config_group_init_type_name'
Add a 'select' statement to Kconfig to ensure it's always there,
which is the common way to enable it for other configfs users.
Fixes: 7dc64244f9e9 ("PCI: endpoint: Add EP function driver to provide NTB functionality")
