Subject: [PATCH -next] PCI: endpoint: fix build error, EP NTB driver uses configfs
Date:   Tue,  2 Feb 2021 12:12:55 -0800

The pci-epf-ntb driver uses configfs APIs, so it should depend on
CONFIGFS_FS to prevent build errors.

ld: drivers/pci/endpoint/functions/pci-epf-ntb.o: in function `epf_ntb_add_cfs':
pci-epf-ntb.c:(.text+0x1b): undefined reference to `config_group_init_type_name'

Fixes: 7dc64244f9e9 ("PCI: endpoint: Add EP function driver to provide NTB functionality")

You may switch to 'select CONFIG_FS_FS' if you feel strongly about it.
