  • 65db43054   USB: convert drivers/usb/* to use module_usb_driver() ... Browse Code »

    This converts the drivers in drivers/usb/* to use the
    module_usb_driver() macro which makes the code smaller and a bit
    simpler.

    Added bonus is that it removes some unneeded kernel log messages about
    drivers loading and/or unloading.

    The id_table field of the struct usb_device_id is constant in
    so it is worth to make the initialization data also constant.

    The semantic match that finds this kind of pattern is as follows:
    (http://coccinelle.lip6.fr/)

    After the last "package" of firmware data is sent to the device, we dereference
    NULL pointer (on access to rec->addr). Fix it.

  • 96de0e252   Convert files to UTF-8 and some cleanups ... Browse Code »

    * Convert files to UTF-8.

    * Also correct some people's names
    (one example is Eißfeldt, which was found in a source file.
    Given that the author used an ß at all in a source file
    indicates that the real name has in fact a 'ß' and not an 'ss',
    which is commonly used as a substitute for 'ß' when limited to
    7bit.)

    * Correct town names (Goettingen -> Göttingen)

    * Update Eberhard Mönkeberg's address (http://lkml.org/lkml/2007/1/8/313)

  • 16c23f7d8   [PATCH] USB: Emagic USB firmware loading fixes ... Browse Code »

    It's become apparent as machines get faster that the emagic kernel firmware
    loaders (based on the ezusb loader) have a reset race. a 400MHz TiBook
    never tripped it, but a 2GHz Pentium M seems to hit it about 30% of the
    time. The bug is seen as a hung USB box and the kernel error:

    drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware:
    error = -110

    The patch below inserts a delay after deasserting reset to allow the box to
    settle before a new command is issued. This affects only device startup.

    Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
