The scanner (here DS3508) always returns 64 bytes per urb buffer. The first
byte indicates the data length used in the current buffer. There even was
a comment describing this. But the comment also said that we'll send
everything in the buffer to the tty layer. That means sending the actual
barcode data and lots of trailing zeroes. This patch lets the driver only
send the real data.

The driver used usb_get_serial_data(port->serial) which compiled but resulted
in a NULL pointer being returned (and subsequently used). I did not go deeper
into this but I guess this is a regression.

The current code prints all wMaxPacketSize content at endpoint
descriptor, if there is a high speed, high bandwidth endpoint,
it may confuse the users, eg, if there are 3 transactions during
microframe, it will print "wMaxPacket 1400" for packet content.
This commit splits wMaxpacketSize and transaction numbers for
output messages.

USB-serial updates for v4.3-rc1

Here's a fix for a long-standing issue with the pl2303 divisor
calculations that affects some non-standard baudrates that were enabled
in v3.18.

Adding support for newer Edgeport devices and firmware required changes
to the io_ti driver and also exposed some issues with the driver's
current firmware handling.

Included is also a URL comment-typo fix.

The main changes are adding several system interfaces for

Others are tiny improvements, like more well siTD supports,

usb: patches for v4.3 merge window

New support for Allwinne SoC on the MUSB driver has been added to the list of
glue layers. MUSB also got support for building all DMA engines in one binary;
this will be great for distros.

DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on
tracing to debug DWC3. There was also a fix for memory corruption with EP0 when
maxpacket size transfers are > 512 bytes.

Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are
now required to set these flags up when adding endpoints to the framework.

Other than these, we have the usual set of miscelaneous cleanups and minor
fixes.
