  • 1781e78c6   ALSA: ak411x: Fix race of reinit() calls ... Browse Code »

    Protect the call with a mutex, as this may be called in parallel
    (either from the PCM rate change and the clock change).

  • 1293617cd   ALSA: ak411x: Add PM helper functions ... Browse Code »

    Define snd_ak4114_suspend() and snd_ak4114_resume() functions to
    handle PM properly, stopping and restarting the work at PM.
    Currently only ice1712/juli.c deals with the PM and ak4114, so fix the
    calls there appropriately.

    The same PM functions are defined in ak4113.c, too, although they
    aren't currently called yet (ice1712/quartet.c may be enhanced to
    support PM later).

    When ak4114 work calls its callback and the callback invokes
    ak4114_reinit(), it stalls due to flush_delayed_work(). For avoiding
    this, control the reentrance by introducing a refcount. Also
    flush_delayed_work() is replaced with cancel_delayed_work_sync().

    The exactly same bug is present in ak4113.c and fixed as well.
