  • d47e1e7c4   s5p-cec: mark PM functions as __maybe_unused again ... Browse Code »

    commit eadf081146ec327d6fbbb6aff28e3d9aac329dc6 upstream.

    A bugfix removed the two callers of s5p_cec_runtime_suspend
    and s5p_cec_runtime_resume, leading to the return of a harmless
    warning that I had previously fixed in commit aee8937089b1
    ("[media] s5p_cec: mark suspend/resume as __maybe_unused"):

    staging/media/s5p-cec/s5p_cec.c:234:12: error: ‘s5p_cec_runtime_suspend’ defined but not used [-Werror=unused-function]
    staging/media/s5p-cec/s5p_cec.c:242:12: error: ‘s5p_cec_runtime_resume’ defined but not used [-Werror=unused-function]

    This adds the __maybe_unused annotations to the function that
    were not removed and that are now unused when CONFIG_PM
    is disabled.

    Fixes: 57b978ada073 ("[media] s5p-cec: fix system and runtime PM integration")

    Pull staging and IIO updates from Greg KH:
    "Here is the big staging and IIO driver pull request for 4.9-rc1.

    There are a lot of patches in here, the majority due to the
    drivers/staging/greybus/ subsystem being merged in with full
    development history that went back a few years, in order to preserve
    the work that those developers did over time.

    Lots and lots of tiny cleanups happened in the tree as well, due to
    the Outreachy application process and lots of other developers showing
    up for the first time to clean code up. Along with those changes, we
    deleted a wireless driver, and added a raspberrypi driver (currently
    marked broken), and lots of new iio drivers.

    Overall the tree still shrunk with more lines removed than added,
    about 10 thousand lines removed in total. Full details are in the very
    long shortlog below.

    All of this has been in the linux-next tree with no issues. There will
    be some merge problems with other subsystem trees, but those are all
    minor problems and shouldn't be hard to work out when they happen
    (MAINTAINERS and some lustre build problems with the IB tree)"

    And furter from me asking for clarification about greybus:
    "Right now there is a phone from Motorola shipping with this code (a
    slightly older version, but the same tree), so even though Ara is not
    alive in the same form, the functionality is happening. We are working
    with the developers of that phone to merge the newer stuff in with
    their fork so they can use the upstream version in future versions of
    their phone product line.

    Toshiba has at least one chip shipping in their catalog that
    needs/uses this protocol over a Unipro link, and rumor has it that
    there might be more in the future.

    There are also other users of the greybus protocols, there is a talk
    next week at ELC that shows how it is being used across a network
    connection to control a device, and previous ELC talks have showed the
    protocol stack being used over USB to drive embedded Linux boards.
    I've also talked to some people who are starting to work to add a host
    controller driver to control arduinos as the greybus PHY protocols are
    very useful to control a serial/i2c/spio/whatever device across a
    random physical link, as it is a way to have a self-describing device
    be attached to a host without needing manual configuration.

    So yes, people are using it, and there is still the chance that it
    will show up in a phone/laptop/tablet/whatever from Google in the
    future as well, the tech isn't dead, even if the original large phone
    project happens to be"

    Building with -Wmaybe-uninitialized reveals the use on an uninitialized

    firmware before version 2 is used:

    drivers/staging/media/pulse8-cec/pulse8-cec.c:447:2: error: 'pa' may be used uninitialized in this function [-Werror=maybe-uninitialized]

    This sets the address to CEC_PHYS_ADDR_INVALID in this case, so we don't
    try to write back the uninitialized data to the device.

    When the configuration is changed, they are also written to the adapter.
    This allows the adapter to continue operating in autonomous mode with
    the same settings when it is disconnected from the driver (typically by
    going into suspend). For adapters with firmware version 2 or greater, the
    settings are also persisted in EEPROM.

    A new module parameter is added to optionally also use the configuration
    already present in the adapter when it is connected. This option is
    enabled by default.

    When a new configuration is written, the autonomous mode is
    automatically enabled. When the device is unconfigured, autonomous mode
    is disabled.
