Subject: [PATCH] usb: serial: mos7840: Fixup mos7840_chars_in_buffer()

commit 5c263b92f828af6a8cf54041db45ceae5af8f2ab upstream.

 * Use the buffer content length as opposed to the total buffer size.  This can
   be a real problem when using the mos7840 as a usb serial-console as all
   kernel output is truncated during boot.
