    kconfig: fix undesirable side effect of adding "visible" menu attribute

    This lead to non-selected, non-user-selectable options to be written
    out to .config. This is not only pointless, but also preventing the
    user to be prompted should any of those options eventually become
    visible (e.g. by de-selecting the *_AUTO options the "visible"
    attribute was added for.

    Furthermore it is quite logical for the "visible" attribute of a menu
    to control the visibility of all contained prompts, which is what the
    patch does.

    sound: Prevent buffer overflow in OSS load_mixer_volumes

    The load_mixer_volumes() function, which can be triggered by
    unprivileged users via the SOUND_MIXER_SETLEVELS ioctl, is vulnerable to
    a buffer overflow.  Because the provided "name" argument isn't
    guaranteed to be NULL terminated at the expected 32 bytes, it's possible
    to overflow past the end of the last element in the mixer_vols array.
    Further exploitation can result in an arbitrary kernel write (via
    subsequent calls to load_mixer_volumes()) leading to privilege
    escalation, or arbitrary kernel reads via get_mixer_levels().  In
    addition, the strcmp() may leak bytes beyond the mixer_vols array.

    Sjoerd Simons reports that, without using position_fix=1, recording
    experiences overruns. Work around that by applying the LPIB quirk
    for his hardware.

    ASoC: codecs: Add missing control_type initialization

    Some codec drivers do not initialize the control_type field in their private
    device struct, but still use it when calling snd_soc_codec_set_cache_io.
    This patch fixes the issue by properly initializing it in the drivers probe
    functions.

    ASoC: codecs: wm8741: Fix register cache incoherency

    The multi-component patch(commit f0fba2ad1) moved the allocation of the
    register cache from the driver to the ASoC core. Most drivers where adjusted to
    this, but the wm8741 driver still uses its own register cache for its
    private functions, while functions from the ASoC core use the generic cache.
    Thus we end up with two from each other incoherent caches, which can lead to
    undefined behaviour.
    This patch fixes the issue by changing the wm8741 driver to use the
    generic register cache in its private functions.
