  • 46797a2ad   i2c: remove unnecessary OOM messages ... Browse Code »

    The site-specific OOM messages are unnecessary, because they
    duplicate the MM subsystem generic OOM message. For example,
    k.alloc and v.alloc failures use dump_stack().

  • 5e47eec00   i2c: i2c-eg20t: do not print error message in syslog if no ACK received ... Browse Code »

    Using the i2c-eg20t driver and call i2cdetect or probe on the bus,
    the driver will print a lot of error messages if there was no ACK
    received.

    i2cdetect normally print a table with all the available devices. If there
    is no device on the address, the table will be empty.
    Currently with the i2c-eg20t driver, the table is not visible because
    the error messages destroy the table.

    Error message: pch_i2c_getack return -71

    This patch prevent the driver to print the messages to syslog.
    The pch_i2c_wait_for_check_xfer function is the only one who is
    calling pch_i2c_getack, so we can delete the function and add the
    read to pch_i2c_wait_for_check_xfer.
    If no ACK is received, the Message will be printed as a dbg
    message.

    Fixed print message to be a one liner so we can grep for the
    error message.

    Tested on Intel Atom E6xx and Eg20t Chipset.

  • 55827f4aa   i2c: Remove unneeded xxx_set_drvdata(..., NULL) calls ... Browse Code »

    There is simply no reason to be manually setting the private driver
    data to NULL in the remove/fail to probe cases. This is just extra
    cruft code that can be removed.

    A few notes:
    * Nothing relies on drvdata being set to NULL.
    * The __device_release_driver() function eventually calls
    dev_set_drvdata(dev, NULL) anyway, so there's no need to do it
    twice.
    * I verified that there were no cases where xxx_get_drvdata() was
    being called in these drivers and checking for / relying on the NULL
    return value.

    This could be cleaned up kernel-wide but for now just take the baby
    step and remove from the i2c subsystem.

  • 0b255e927   i2c: remove __dev* attributes from subsystem ... Browse Code »

    CONFIG_HOTPLUG is going away as an option. As result the __dev*
    markings will be going away.

    Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
    and __devexit.

    Convert the drivers in drivers/i2c/busses/* to usemodule_pci_driver()
    macro which makes the code smaller and a bit simpler.

  • 3527bd504   i2c: Convert to DEFINE_PCI_DEVICE_TABLE ... Browse Code »

    Convert static struct pci_device_id *[] to static DEFINE_PCI_DEVICE_TABLE
    tables.

    Use DEFINE_PCI_DEVICE_TABLE ensures we make the pci_device_id table const
    and marked as __devinitconst.

    This also fixes some warnings from checkpatch:
    e.g.
    WARNING: Use DEFINE_PCI_DEVICE_TABLE for struct pci_device_id
    #1096: FILE: i2c/busses/i2c-intel-mid.c:1096:

  • 0d5fb5ea7   i2c-eg20t: correct the driver init order of pch_i2c_probe() ... Browse Code »

    Before registering an adapter to i2c subsystem, we need make sure
    driver is ready for incoming i2c xfer, becasue the i2c_add_adapter()
    may trigger a i2c device driver's proble function which may start
    some real i2c xfer. I met this issue when integrating a TSC2007 i2c
    touch screen device with the i2c-eg20t driver.

    This patch will call request_irq() and hw init before calling
    i2c_add_adapter().
