ALSA: seq: Fix init order of snd_seq_device stuff
When the sequencer driver is built in kernel, it may panic at boot because of the uninitialized snd_seq_bus_type. Initialize it properly via subsys_initcall() instead of module_init() to assure that the bus is registered beforehand. Reported-by: Fengguang Wu <fengguang.wu@intel.com> Fixes: 7c37ae5c625a ('ALSA: seq: Rewrite sequencer device binding with standard bus') Signed-off-by: Takashi Iwai <tiwai@suse.de>
