  • ef24ba709   powerpc: Remove all usages of NO_IRQ ... Browse Code »

    NO_IRQ has been == 0 on powerpc for just over ten years (since commit
    0ebfff1491ef ("[POWERPC] Add new interrupt mapping core and change
    platforms to use it")). It's also 0 on most other arches.

    Although it's fairly harmless, every now and then it causes confusion
    when a driver is built on powerpc and another arch which doesn't define
    NO_IRQ. There's at least 6 definitions of NO_IRQ in drivers/, at least
    some of which are to work around that problem.

    So we'd like to remove it. This is fairly trivial in the arch code, we
    just convert:

    if (irq == NO_IRQ) to if (!irq)
    if (irq != NO_IRQ) to if (irq)
    irq = NO_IRQ; to irq = 0;
    return NO_IRQ; to return 0;

    And a few other odd cases as well.

    At least for now we keep the #define NO_IRQ, because there is driver
    code that uses NO_IRQ and the fixes to remove those will go via other
    trees.

    Note we also change some occurrences in PPC sound drivers, drivers/ps3,
    and drivers/macintosh.

  • b268c34e5   ALSA: ppc/awacs: shut up maybe-uninitialized warning ... Browse Code »

    The awacs sound driver produces a false-positive warning in ppc64_defconfig:

    sound/ppc/awacs.c: In function 'snd_pmac_awacs_init':
    include/sound/control.h:219:9: warning: 'master_vol' may be used uninitialized in this function [-Wmaybe-uninitialized]

    I haven't come up with a good way to rewrite the code to avoid the
    warning, so here is a bad one: I initialize the variable before
    the conditionall initialization so gcc no longer has to worry about
    it.

  • 952bbcb07   PCI: Remove includes of asm/pci-bridge.h ... Browse Code »

    Drivers should include asm/pci-bridge.h only when they need the arch-
    specific things provided there. Outside of the arch/ directories, the only
    drivers that actually need things provided by asm/pci-bridge.h are the
    powerpc RPA hotplug drivers in drivers/pci/hotplug/rpa*.

    Remove the includes of asm/pci-bridge.h from the other drivers, adding an
    include of linux/pci.h if necessary.

  • 28760c195   ALSA: ppc: keywest: check if DEQ was already instantiated ... Browse Code »

    Due to changes in i2c-powermac, for some Macs the DEQ is instantiated
    now in i2c-powermac while some need the instantiation here in the
    keywest sound driver. The proper fix is to convert this driver to AOA.
    Until then support both ways of instantiation. Before this patch, some
    Macs lost sound because the sound driver failed when instantiating the
    DEQ for the second time.

  • f57187267   powerpc: Move Power Macintosh drivers to generic byteswappers ... Browse Code »

    ppc has special instruction forms to efficiently load and store values
    in non-native endianness. These can be accessed via the arch-specific
    {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h.

    However, gcc is perfectly capable of generating the byte-reversing
    load/store instructions when using the normal, generic cpu_to_le*() and
    le*_to_cpu() functions eaning the arch-specific functions don't have much
    point.

    Worse the "le" in the names of the arch specific functions is now
    misleading, because they always generate byte-reversing forms, but some
    ppc machines can now run a little-endian kernel.

    To start getting rid of the arch-specific forms, this patch removes them
    from all the old Power Macintosh drivers, replacing them with the
    generic byteswappers.

    "Here's the set of driver core patches for 3.19-rc1.

    They are dominated by the removal of the .owner field in platform

    Other than that, a few minor driver core and debugfs changes. There

    acked by the wireless maintainers as they relied on the debugfs
    changes.

    There are a bunch of users open coding the for_each_node_by_name() by
    calling of_find_node_by_name() directly instead of using the macro. This
    is getting in the way of some cleanups, and the possibility of removing
    of_find_node_by_name() entirely. Clean it up so that all the users are
