  • d69bb92e4   ALSA: asihpi: fix kernel memory disclosure ... Browse Code »

    Some elements in hr are not cleared before being copied to user space,
    leaking kernel heap memory to user space. For example, this happens in
    the error handling code for the HPI_ADAPTER_DELETE case. Zero the memory
    before it's copied.

  • 6769e988b   ALSA: constify snd_pcm_ops structures ... Browse Code »

    Check for snd_pcm_ops structures that are only stored in the ops field of a
    snd_soc_platform_driver structure or passed as the third argument to
    snd_pcm_set_ops. The corresponding field or parameter is declared const,
    so snd_pcm_ops structures that have this property can be declared as const
    also.

    The semantic patch that makes this change is as follows:

    //

    identifier i;

    Nothing in uses anything from , so
    remove it from there and fix up the resulting build problems
    triggered on x86 {64|32}-bit {def|allmod|allno}configs.

    The breakages were triggering in places where x86 builds relied
    on vmalloc() facilities but did not include
    explicitly and relied on the implicit inclusion via .

    Also add:

    - to
    - to

    ... which were two other implicit header file dependencies.

  • d18132aa1   ALSA: asihpi: Remove always NULL parameter ... Browse Code »

    snd_asihpi_hpi_new() takes a pointer to a pointer of a hwdep where if this
    parameter is provided the newly allocated hwdep is stored. All callers pass
    NULL though, so remove the parameter. This makes the code a bit cleaner and
    shorter.

    Add a new helper function snd_pcm_stop_xrun() to the standard sequnce
    lock/snd_pcm_stop(XRUN)/unlock by a single call, and replace the
    existing open codes with this helper.

    The function checks the PCM running state to prevent setting the wrong
    state, too, for more safety.

  • 20a24225d   ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at remove ... Browse Code »

    As drvdata is cleared to NULL at probe failure or at removal by the
    driver core, we don't have to call pci_set_drvdata(pci, NULL) any
    longer in each driver.

    The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
    hda_intel.c. Since this function itself releases the card instance,
    we need to clear drvdata here as well, so that it won't be released
    doubly in the remove callback.
