ALSA: seq: Remove superfluous snd_seq_queue_client_leave_cells() call
With the previous two fixes for the write / ioctl races: ALSA: seq: Don't allow resizing pool in use ALSA: seq: More protection for concurrent write and ioctl races the cells aren't any longer in queues at the point calling snd_seq_pool_done() in snd_seq_ioctl_set_client_pool(). Hence the function call snd_seq_queue_client_leave_cells() can be dropped safely from there. Suggested-by: Nicolai Stange <nstange@suse.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
