  • 00e4bbc8c   net: can: use platform_{get,set}_drvdata() ... Browse Code »

    Use the wrapper functions for getting and setting the driver data using
    platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
    so we can directly pass a struct platform_device.

    Also, unnecessary dev_set_drvdata() is removed, because the driver core
    clears the driver data to NULL after device_release or on probe failure.

  • 3c8ac0f2a   can: remove __dev* attributes ... 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.

  • c2fd03a01   drivers: net: Remove casts to same type ... Browse Code »

    Adding casts of objects to the same type is unnecessary
    and confusing for a human reader.

    For example, this cast:

    int y;
    int *p = (int *)&y;

    I used the coccinelle script below to find and remove these
    unnecessary casts. I manually removed the conversions this
    script produces of casts with __force, __iomem and __user.

    @@
    type T;
    T *p;
    @@

    - (T *)p
    + p

  • 871d33725   net/can: convert drivers/net/can/* to use module_platform_driver() ... Browse Code »

    This patch converts the drivers in drivers/net/can/* to use the
    module_platform_driver() macro which makes the code smaller and a bit
    simpler.

  • cfbf7586b   can: bfin_can: auto-calculate accessor sizes ... Browse Code »

    Since we have a struct that defines the sizes of the registers, we don't
    need to explicitly use the 16bit read/write helpers. Let the code figure
    out which size access to make based on the size of the C type.

    There should be no functional changes here.

  • 9118f08a7   can: bfin_can: simplify xmit id1 setup ... Browse Code »

    If we look closely, the 4 writes to TRANSMIT_CHL.id1 can be collapsed
    down into much simpler code. So do just that.

    This also fixes a build failure due to the I/O macros no longer
    getting pulled in. Their minor (and accidental) usage here gets
    dropped as part of the unification.

    Now that core network takes care of trans_start updates, dont do it
    in drivers themselves, if possible. Drivers can avoid one cache miss
    (on dev->trans_start) in their start_xmit() handler.

    Exceptions are NETIF_F_LLTX drivers

  • 3ccd4c616   can: Unify droping of invalid tx skbs and netdev stats ... Browse Code »

    To prevent the CAN drivers to operate on invalid socketbuffers the skbs are
    now checked and silently dropped at the xmit-function consistently.

    Also the netdev stats are consistently using the CAN data length code (dlc)
    for [rx|tx]_bytes now.

  • c7cd606f6   can: Fix data length code handling in rx path ... Browse Code »

    A valid CAN dataframe can have a data length code (DLC) of 0 .. 8 data bytes.

    When reading the CAN controllers register the 4-bit value may contain values
    from 0 .. 15 which may exceed the reserved space in the socket buffer!

    The ISO 11898-1 Chapter 8.4.2.3 (DLC field) says that register values > 8
    should be reduced to 8 without any error reporting or frame drop.

    This patch introduces a new helper macro to cast a given 4-bit data length
    code (dlc) to __u8 and ensure the DLC value to be max. 8 bytes.

    The different handlings in the rx path of the CAN netdevice drivers are fixed.
