  • b31366f43   i2c: i2c_adapter devices need no driver ... Browse Code »

    Kill i2c_adapter_driver as it doesn't make sense and it prevents
    further i2c-core cleanups. i2c_adapter devices are virtual devices
    (ex-class devices) and as such they don't need a driver.

  • fccb56e4d   i2c: Kill i2c_adapter.class_dev ... Browse Code »

    Kill i2c_adapter.class_dev. Instead, set the class of i2c_adapter.dev
    to i2c_adapter_class, so that a symlink will be created for every
    i2c_adapter in /sys/class/i2c-adapter.

    The same change must be mirrored to i2c-isa as it duplicates some
    of the i2c-core functionalities.

    User-space tools and libraries might need some adjustments. In
    particular, libsensors from lm_sensors 2.10.3 or later is required for
    proper discovery of i2c adapter names after this change.

  • dc87c3985   libata: honour host controllers that want just one host ... Browse Code »

    The Marvell IDE interface on my machine would hit a BUG_ON() in
    lib/iomem.c because it was calling ata_pci_init_one() specifying just a
    single port on the host, but that would actually end up trying to
    initialize two ports, the second one with bogus information.

    This fixes "ata_pci_init_one()" so that it actually passes down the
    n_ports variable that it got from the low-level driver to the host
    allocation routine ("ata_host_alloc_pinfo()"), which results in the ATA
    layer actually having the correct port number information.

    And in order to make it all work, I also needed to fix a few places that
    had incorrectly hard-coded the fact that a host always had exactly two
    ports (both ata_pci_init_bmdma() and ata_request_legacy_irqs() would
    just always iterate over both ports).

  • e8c9c5026   power management: implement pm_ops.valid for everybody ... Browse Code »

    Almost all users of pm_ops only support mem sleep, don't check in .valid and
    don't reject any others in .prepare so users can be confused if they check
    /sys/power/state, especially when new states are added (these would then
    result in s-t-r although they're supposed to be something different).

    This patch implements a generic pm_valid_only_mem function that is then
    exported for users and puts it to use in almost all existing pm_ops.
