    ALSA: compress: Fix regression on compressed capture streams · 4475f8c4
    Charles Keepax authored
    A previous fix to the stop handling on compressed capture streams causes
    some knock on issues. The previous fix updated snd_compr_drain_notify to
    set the state back to PREPARED for capture streams. This causes some
    issues however as the handling for snd_compr_poll differs between the
    two states and some user-space applications were relying on the poll
    failing after the stream had been stopped.
    
    To correct this regression whilst still fixing the original problem the
    patch was addressing, update the capture handling to skip the PREPARED
    state rather than skipping the SETUP state as it has done until now.
