Breno Leitao 77461c1081 net: dqs: Do not use extern for unused dql_group ... When CONFIG_DQL is not enabled, dql_group should be treated as a dead declaration. However, its current extern declaration assumes the linker will ignore it, which is generally true across most compiler and architecture combinations. But in certain cases, the linker still attempts to resolve the extern struct, even when the associated code is dead, resulting in a linking error. For instance the following error in loongarch64: >> loongarch64-linux-ld: net-sysfs.c:(.text+0x589c): undefined reference to `dql_group' Modify the declaration of the dead object to be an empty declaration instead of an extern. This change will prevent the linker from attempting to resolve an undefined reference.
