Subject: [34-longterm 060/247] drivers: update to pl2303 usb-serial to support Motorola cables

From: Dario Lombardo <dario.lombardo@...eroo.it>

                   -------------------
    This is a commit scheduled for the next v2.6.34 longterm release.
    If you see a problem with using this for longterm, please comment.
                   -------------------

commit 96a3e79edff6f41b0f115a82f1a39d66218077a7 upstream.

Added 0x0307 device id to support Motorola cables to the pl2303 usb
serial driver. This cable has a modified chip that is a pl2303, but
declares itself as 0307. Fixed by adding the right device id to the
supported devices list, assigning it the code labeled
PL2303_PRODUCT_ID_MOTOROLA.
