[PATCH 0/2] wifi: mt76: unlink TWT flows when MCU ADD fails

[Zhao Li]

mt7915 and mt7996 link a TWT flow into the device list before asking the
MCU to add the agreement. If that request fails, the accounting masks
remain clear but the embedded flow node stays linked.

A retry can corrupt the list by reinitializing the same linked node. If
the station is removed instead, the mask-gated teardown skips the flow,
leaving a dangling node for later scheduling and debugfs walks. The two
patches restore the list to its pre-request state on the MCU ADD failure
path, split per driver because their Fixes targets differ.

MCU DELETE failures are deliberately outside this series. Deciding
whether to drop host bookkeeping while firmware may retain an agreement
requires separate ownership and accounting treatment.
