The emu1010_firmware_thread() checks the previous dock status, but a wrong register is recorded as the last status when the dock is plugged in. Usually this isn't a big issue since this value gets overwritten by the next loop after one second. But when a dock is unplugged immediately after plugging, it means essentially missing undock handling.
This patch addresses it by remembering the correct register value.
