  • This is recreated driver for the FM module found on Miro
    PCM20 sound cards. This driver was removed around the 2.6.2x
    kernels because it relied on the removed OSS module. Now, it
    uses a current ALSA module (snd-miro) and is adapted to v4l2
    layer.

    It provides only basic functionality: frequency changing and
    FM module muting.

  • Commit 0c570cdeb8fdfcb354a3e9cd81bfc6a09c19de0c
    (PM / yenta: Fix cardbus suspend/resume regression) caused resume to
    fail on systems with two CardBus bridges. While the exact nature
    of the failure is not known at the moment, it can be worked around by
    splitting the yenta resume into an early part, executed during the
    early phase of resume, that will only resume the socket and power it
    up if there was a card in it during suspend, and a late part,
    executed during "regular" resume, that will carry out all of the
    remaining yenta resume operations.

    Fixes http://bugzilla.kernel.org/show_bug.cgi?id=14334, which is a
    listed regression from 2.6.31.

  • The driver always ends a read with a STOP condition which
    breaks subsequent I2C reads/writes in the same transaction as
    these expect to do a repeated START(ReSTART).

    This will also help I2C multimaster as the bus will not be released
    after the first read, but when the whole transaction ends.

  • In commit c1c7af60892070e4b82ad63bbfb95ae745056de0 ("drm/i915: force
    mode set at lid open time") the intel graphics driver was taught to
    restore the LVDS mode on lid open.

    That caused problems with interaction with the suspend/resume code,
    which commonly runs at the same time (suspend is often caused by the lid
    close event, while lid open is commonly a resume event), which was
    worked around with in commit 06891e27a9b5dba5268bb80e41a283f51335afe7
    ("drm/i915: fix suspend/resume breakage in lid notifier").

    However, in the meantime the lid event code had also grown a user event
    notifier (commit 06324194eee97a51b5f172270df49ec39192d6cc: "drm/i915:
    generate a KMS uevent at lid open/close time"), and now _that_ causes
    problems with suspend/resume and some versions of Xorg reacting to those
    uevents by setting the mode.

    So this effectively reverts that commit 06324194ee, and makes the lid
    open protection logic against suspend/resume more explicit. This fixes
    at least one laptop. See

    http://bugzilla.kernel.org/show_bug.cgi?id=14484

    for more details.

  • Platform drivers registered via platform_driver_probe() can be bound
    to devices only once, upon registration, because discard their probe()
    routines to save memory. Unbinding the driver through sysfs 'unbind'
    leaves the device stranded and confuses users so let's not create
    bind and unbind attributes for such drivers.

    the check was added for another driver to already claim the same device
    on the same bus. But the returned error code was wrong: to modprobe, the
    -EEXIST means that _this_ driver is already installed. It therefore
    doesn't produce the needed error message when _another_ driver is trying
    to register for the same device. Returning -EBUSY fixes the problem.

    The patch "sierra_close() must resume the device before it notifies it

    merged as fix in sierra_close() function.

    The bug fix in sierra_open() function restores the autopm interface

    The bug fix in in stop_read_write_urbs() function assures that both

  • This patch prevents the driver from calling misc_deregister twice on the same
    ressouce when unloading the driver.
    Unloading the driver without this patch results in a Kernel BUG like this:
    Panel driver version 0.9.5 registered on parport0 (io=0x378).
    BUG: unable to handle kernel paging request at 0000000000100108

    This patch fixes this issue, although maybe not in the best way possible :)
