    b43: Dynamically control log verbosity · 060210f9

    Dynamically control the log verbosity with a module parameter.
    This enables us to dynamically enable debugging messages (or disable
    info, warn, error messages) via module parameter or /sys/module/b43/parameters/verbose.
    This increases the module size by about 3k. But in practice it reduces the
    module size for the user, because some distributions ship the b43 module
    with CONFIG_B43_DEBUG set, which increases the module by about 15k.
    So with this patch applied, distributions should really _disable_ CONFIG_B43_DEBUG.
    There is no reason to keep it in a production-release kernel.
    So we have a net reduction in size by about 12k.
    This patch also adds a printk of the wireless core revision, so people
    don't have to enable SSB debugging to get the wireless core revision.
