Frequently Asked Questions

1

Which systems are relevant to this issue?

Systems using the Linux kernel rt700-sdw SoundWire codec driver are relevant. The problematic path involves the driver's jack detection and jack button delayed-work objects during device removal.

2

What sequence leads to the unsafe removal path?

A jack work item must have been queued while the device was initialized, then the SoundWire slave transitions to SDW_SLAVE_UNATTACHED, which clears hw_init, followed by driver removal. In that sequence, removal can skip draining work that was already queued.

3

How can administrators or developers identify the condition?

The supplied proof of concept caused DEBUG_OBJECTS to report an active timer/work object associated with rt700 jack work during removal. Reviewing traces for queued jack_detect_work or jack_btn_check_work followed by an unattached SoundWire status and remove operation can help identify the affected path.

4

What is the remediation behavior?

The corrected removal path cancels and drains the delayed jack work unconditionally, because the work objects are initialized during rt700_init(). The provided stable-kernel references contain the resolved changes.
