  • Switch to resource-managed function devm_led_classdev_register instead
    of led_classdev_register and remove unneeded led_classdev_unregister.

    Also, remove platform_set_drvdata in probe function and the remove
    function, pm860x_led_remove as it is now has nothing to do.

    The Coccinelle semantic patch used to make this change is as follows:
    //
    @platform@
    identifier p, probefn, removefn;
    @@
    struct platform_driver p = {
    .probe = probefn,
    .remove = removefn,
    };

    @prb@
    identifier platform.probefn, pdev;
    expression e;
    @@
    probefn(struct platform_device *pdev, ...) {
    ...
    e =
    - led_classdev_register
    + devm_led_classdev_register
    (...);
    ...
    ?- led_classdev_unregister(...);
    ...
    }
    @remove depends on prb@
    identifier platform.removefn;
    @@
    removefn(...) {
    ...
    ?- led_classdev_unregister(...);

  • for_each_child_of_node performs an of_node_get on each iteration, so
    a break out of the loop requires an of_node_put.

    A simplified version of the semantic patch that fixes this problem is as
    follows (http://coccinelle.lip6.fr):

    //
    @@
    local idexpression n;
    expression e,r;
    @@

    for_each_child_of_node(r,n) {
    ...
    (
    of_node_put(n);
    |
    e = n
    |
    + of_node_put(n);
    ? break;
    )
    ...
    }
    ... when != n

  • 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.

  • of_find_node_by_name() returns a node pointer with refcount incremented, use
    of_node_put() on it when done.

    of_find_node_by_name() will call of_node_put() against from parameter,
    thus we also need to call of_node_get(from) before calling
    of_find_node_by_name().

  • Since several sub modules such as backlight, leds and vibrator depend

    the power control of led in pm8606 by unified interface.

  • With the addition of a platform device mfd_cell pointer, MFD drivers
    can go back to passing platform back to their sub drivers.
    This allows for an mfd_cell->mfd_data removal and thus keep the
    sub drivers MFD agnostic. This is mostly needed for non MFD aware
    sub drivers.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.
