+Subject: HID: hid-steam: Don't use cancel_delayed_work_sync in IRQ context
+
+From: Vicki Pfau <vi@endrift.com>
+
+commit b051ffa2aeb2a60e092387b6fb2af1ad42f51a3c upstream.
+
+Lockdep reported that, as steam_do_deck_input_event is called from
+steam_raw_event inside of an IRQ context, it can lead to issues if that IRQ
+occurs while the work to be cancelled is running. By using cancel_delayed_work,
+this issue can be avoided. The exact ordering of the work and the event
+processing is not super important, so this is safe.
+
+Fixes: cd438e57dd05 ("HID: hid-steam: Add gamepad-only mode switched to by holding options")
