ALSA: emu10k1: Use workqueue instead of kthread for emu1010 fw polling
This patch is a cleanup of EMU1010 dock probing code in emu10k1 driver to use work instead of kthread in a loop. The work is lighter and easier to control than kthread, in general. Instead of a loop with the explicit sleep, we do simply delayed-schedule the work. At suspend/resume callbacks, the work is canceled and restarted, respectively.
