Before c01908a14bf73 ("HID: input: add mapping for "Toggle Display" key") this usage was being mapped to 'Relative.Misc'. After the patch it's simply ignored (usage->type == 0 & usage->code == 0). Which ultimately makes hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no usage->type. We shouldn't rely on a mapping for that usage as it's nonstandard and doesn't really map to an input event. So we bypass the mapping and make sure the custom event handling properly handles both reports.

Valve reported a kernel crash on Ubuntu 18.04 when disconnecting a DS4 gamepad while rumble is enabled. This issue is reproducible with a frequency of 1 in 3 times in the game Borderlands 2 when using an automatic weapon, which triggers many rumble operations. We found the issue to be a race condition between sony_remove and the final device destruction by the HID / input system. The problem was that sony_remove didn't clean some of its work_item state in "struct sony_sc". After sony_remove work, the corresponding evdev node was around for sufficient time for applications to still queue rumble work after "sony_remove". On pre-4.19 kernels the race condition caused a kernel crash due to a NULL-pointer dereference as "sc->output_report_dmabuf" got freed during sony_remove. On newer kernels this crash doesn't happen due the buffer now being allocated using devm_kzalloc. However we can still queue work, while the driver is an undefined state. This patch fixes the described problem, by guarding the work_item "state_worker" with an initialized variable, which we are setting back to 0 on cleanup.
