  • The kzalloc() function has a 2-factor argument form, kcalloc(). This
    patch replaces cases of:

    kzalloc(a * b, gfp)

    with:
    kcalloc(a * b, gfp)

    as well as handling cases of:

    kzalloc(a * b * c, gfp)

    with:

    kzalloc(array3_size(a, b, c), gfp)

    as it's slightly less ugly than:

    kzalloc_array(array_size(a, b), c, gfp)

    This does, however, attempt to ignore constant size factors like:

    kzalloc(4 * 1024, gfp)

    though any constants defined via macros get caught up in the conversion.

    Any factors with a sizeof() of "unsigned char", "char", and "u8" were
    dropped, since they're redundant.

    The Coccinelle script used for this was:

  • Currently, pinctrl_register() just returns NULL on error, so the
    callers can not know the exact reason of the failure.

    Some of the pinctrl drivers return -EINVAL, some -ENODEV, and some
    -ENOMEM on error of pinctrl_register(), although the error code
    might be different from the real cause of the error.

    This commit reworks pinctrl_register() to return the appropriate
    error code and modifies all of the pinctrl drivers to use IS_ERR()
    for the error checking and PTR_ERR() for getting the error code.

    "pinctrl: avoid duplicated calling enable_pinmux_setting for a pin"
    removed the .disable callback from the struct pinmux_ops,
    making the .enable() callback the only remaining callback.

    However .enable() is a bad name as it seems to imply that a
    muxing can also be disabled. Rename the callback to .set_mux()
    and also take this opportunity to clean out any remaining
    mentions of .disable() from the documentation.

  • Implement support for pinctrl on lantiq/xway socs. The IO core found on these
    socs has the registers for pinctrl, pinconf and gpio mixed up in the same
    register range. As the gpio_chip handling is only a few lines, the driver also
    implements the gpio functionality. This obseletes the old gpio driver that was
    located in the arch/ folder.
