    usb-serial: don't release unregistered minors
    
    commit 0282b7f2a874e72c18fcd5a112ccf67f71ba7f5c upstream
    
    This patch (as1121) fixes a bug in the USB serial core.  When a device
    is unregistered, the core will give back its minors -- even if the
    device hasn't been assigned any!
    
    The patch reserves the highest minor value (255) to mean that no minor
    was assigned.  It also removes some dead code and does a small style
    fixup.

    USB: usb-storage: quirk around v1.11 firmware on Nikon D4
    
    commit b9a097f26e55968cbc52e30a4a2e73d32d7604ce upstream
    
    usb-storage: quirk around v1.11 firmware on Nikon D40
    
    https://bugzilla.redhat.com/show_bug.cgi?id=454028
    Just as in earlier firmware versions, we need to perform this
    quirk for the latest version too.
    
    Speculatively do the entry for the D80 too, as they seem to
    have the same firmware problems historically.

    V4L/DVB (9053): fix buffer overflow in uvc-video
    
    Commit fe6c700ff34e68e1eb7991e9c5d18986d0005ac1 upstream
    
    V4L/DVB (9053): fix buffer overflow in uvc-video
    
    There is a buffer overflow in drivers/media/video/uvc/uvc_ctrl.c:
    
    INFO: 0xf2c5ce08-0xf2c5ce0b. First byte 0xa1 instead of 0xcc
    INFO: Allocated in uvc_query_v4l2_ctrl+0x3c/0x239 [uvcvideo] age=13 cpu=1 pid=4975
    ...
    
    A fixed size 8-byte buffer is allocated, and a variable size field is read
    into it; there is no particular bound on the size of the field (it is
    dependent on hardware and configuration) and it can overflow [also
    verified by inserting printk's.]
    
    The patch attempts to size the buffer to the correctly.

    V4L/DVB (8617): uvcvideo: don't use stack-based buffers for USB transfers.
    
    commit 04793dd041bbb88a39b768b714c725de2c339b51 upstream
    
    Data buffers on the stack are not allowed for USB I/O. Use dynamically
    allocated buffers instead.

    V4L/DVB (8498): uvcvideo: Return sensible min and max values when querying a boolean control.
    
    commit 54812c77bc830e2dbcb62b4c6d8a9c7f97cfdd1b upstream
    
    [required to get the following two patches to apply]
    
    Although the V4L2 spec states that the minimum and maximum fields may not be
    valid for control types other than V4L2_CTRL_TYPE_INTEGER, it makes sense
    to set the bounds to 0 and 1 for boolean controls instead of returning
    uninitialized values.

There's probably also a handful of stability fixes that could be useful, and of course dozens of changes for hardware or architectures we don't use :-)
