    Subject[PATCH 06/29] platform/x86: amilo-rfkill: Convert to platform remove callback returning void
    Date
    The .remove() callback for a platform driver returns an int which makes
    many driver authors wrongly assume it's possible to do error handling by
    returning an error code. However the value returned is (mostly) ignored
    and this typically results in resource leaks. To improve here there is a
    quest to make the remove callback return void. In the first step of this
    quest all drivers are converted to .remove_new() which already returns
    void.

    Trivially convert this driver from always returning zero in the remove
    callback to the void returning variant.
