From: Matt Chen <[email protected]> The issue was found when entering suspend and resume. It triggers a warning in: mac80211/key.c: ieee80211_enable_keys() ... WARN_ON_ONCE(sdata->crypto_tx_tailroom_needed_cnt || sdata->crypto_tx_tailroom_pending_dec); ...
It points out sdata->crypto_tx_tailroom_pending_dec isn't cleaned up successfully in a delayed_work during suspend. Add a flush_delayed_work to fix it.
