Series net: avoid to remove module when its debugfs is being used | expand

Commit Message

Taehee Yoo Nov. 7, 2020, 5:21 p.m. UTC 
If THIS_MODULE is not set, the module would be removed while debugfs is
being used.
It eventually makes kernel panic.

Fixes: 5ae212c9273d ("[PATCH] iwlwifi: add read rate scale table debugfs function")
Fixes: 0209dc11c769 ("[PATCH] iwlwifi: add debugfs rate scale stats")
Fixes: 712b6cf57a53 ("iwlwifi: Add debugfs to iwl core")
Fixes: 189a2b5942d6 ("iwlwifi: trigger event log from debugfs")
Fixes: 8ca151b568b6 ("iwlwifi: add the MVM driver")
Fixes: 757cf23b4b4b ("iwlwifi: mvm: add per rate tx stats")
Fixes: 2b55f43f8e47 ("iwlwifi: mvm: Add mem debugfs entry")
Fixes: 93b167c13a3a ("iwlwifi: runtime: sync FW and host clocks for logs")
Fixes: 38167459da50 ("iwlagn: show current rate scale data in debugfs")
Fixes: 87e5666c0722 ("iwlagn: transport handler can register debugfs entries")
Fixes: 16db88ba51d6 ("iwlagn: move dump_csr and dump_fh to transport layer")
