From 706add13676da7ad213b65e92b94af5efc8c4131 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 26 Oct 2023 15:08:04 +0200 Subject: nvme: keyring: fix conditional compilation The keyring and auth functions can be called from both the host and the target side and are controlled by Kconfig options for each of the combinations, but the declarations are controlled by #ifdef checks on the shared Kconfig symbols. This leads to link failures in combinations where one of the frontends is built-in and the other one is a module, and the keyring code ends up in a module that is not reachable from the builtin code: ld: drivers/nvme/host/core.o: in function `nvme_core_exit': core.c:(.exit.text+0x4): undefined reference to `nvme_keyring_exit' ld: drivers/nvme/host/core.o: in function `nvme_core_init': core.c:(.init.text+0x94): undefined reference to `nvme_keyring_init ld: drivers/nvme/host/tcp.o: in function `nvme_tcp_setup_ctrl': tcp.c:(.text+0x4c18): undefined reference to `nvme_tls_psk_default' Address this by moving nvme_keyring_init()/nvme_keyring_exit() into module init/exit functions for the keyring module.
