I added try_access_atomic() for the hard handler on top of v7 [0]. Can you rebase onto that and carry the patch at the front of your series? Then: a) hard handler: try_access_atomic(), return ThreadedIrqReturn::None on = None b) threaded handler: access() c) drop the #[expect(dead_code)] =E2=80=94 Daniel [0] = https://gitlab.collabora.com/dwlsalmeida/for-upstream/-/tree/tyr-hwgate-tr= y-atomic?ref_type=3Dheads=
