Hello:

This patch was applied to netdev/net.git (main)
by Jakub Kicinski [off-list ref]:

On Sat, 15 Aug 2026 23:17:37 +0800 you wrote:
ipa_remove() takes a runtime PM reference before accessing IPA hardware
during teardown. If a concurrent modem start or stop keeps
ipa_modem_stop() busy across both attempts, the callback intentionally
returns without releasing the remaining resources because proceeding
with teardown could crash. That return also skips the matching
pm_runtime_put_noidle(), leaving the callback's usage-count reference
held.

[...]
Here is the summary with links:
