Subject: [PATCH] iwlwifi: dbg: run init_cfg function once per driver load
Git-commit: 42f8a2735cc218b6b372134684d4cd3c1423f123
Patch-mainline: v5.10-rc1
References: git-fixes

Every time we call init_cfg driver appends the enabled triggers
to the active triggers while this should be done only once per
driver load.
