Subject: [PATCH] pl2303: Remove antiquated support for I330 phone

Samsung has just released a portable USB3 SSD, coming in a very small
and nice form factor. It's USB ID is 04e8:8001, which unfortunately is
already used by the pl2303 USB serial driver for the Samsung I330 phone
cradle. This phone was manufactured in 2001, and I seriously doubt it is
still in use on any contemporary networks. Having pl2303 pick up this
device ID results in conflicts with the usb-storage driver, which
handles the newly released portable USB3 SSD. In this patch I remove the
device ID of the old antiquated telephone from the pl2303 driver, so
that usb-storage can handle it.
