From: Arnd Bergmann <[email protected]>
In configurations without CONFIG_NVME_TARGET_TCP_TLS, the keyring
code might not be available, or using it will result in a runtime
failure:
x86_64-linux-ld: vmlinux.o: in function `nvmet_ports_make':
configfs.c:(.text+0x100a211): undefined reference to `nvme_keyring_id'
Add a check to ensure we only check the keyring if there is a chance
of it being used, which avoids both the runtime and link-time
problems.
