    ALSA: seq: Fix potential concurrent access to the deleted pool · 75545304
    Takashi Iwai authored
    The input pool of a client might be deleted via the resize ioctl, the
    the access to it should be covered by the proper locks.  Currently the
    only missing place is the call in snd_seq_ioctl_get_client_pool(), and
    this patch papers over it.
