[ Upstream commit b051ffa2aeb2a60e092387b6fb2af1ad42f51a3c ]
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.
