      USB: gadget: Fix double-free bug in raw_gadget driver · 90bc2af2
      Alan Stern authored
      Re-reading a recently merged fix to the raw_gadget driver showed that
      it inadvertently introduced a double-free bug in a failure pathway.
      If raw_ioctl_init() encounters an error after the driver ID number has
      been allocated, it deallocates the ID number before returning.  But
      when dev_free() runs later on, it will then try to deallocate the ID
      number a second time.
      
      Closely related to this issue is another error in the recent fix: The
      ID number is stored in the raw_dev structure before the code checks to
      see whether the structure has already been initialized, in which case
      the new ID number would overwrite the earlier value.
      
      The solution to both bugs is to keep the new ID number in a local
      variable, and store it in the raw_dev structure only after the check
      for prior initialization.  No errors can occur after that point, so
      the double-free will never happen.

      USB: serial: option: add Quectel EM05-G modem · 33b29dbb
      Yonglin Tan authored
      The EM05-G modem has 2 USB configurations that are configurable via the AT
      command AT+QCFG="usbnet",[ 0 | 2 ] which make the modem enumerate with
      the following interfaces, respectively:
      
      "RMNET"	: AT + DIAG + NMEA + Modem + QMI
      "MBIM"	: MBIM + AT + DIAG + NMEA + Modem
      
      The detailed description of the USB configuration for each mode as follows:

      USB: serial: pl2303: add support for more HXN (G) types · ae60aac5
      Johan Hovold authored
      Add support for further HXN (G) type devices (GT variant, GL variant, GS
      variant and GR) and document the bcdDevice mapping.
      
      Note that the TA and TB types use the same bcdDevice as some GT and GE
      variants, respectively, but that the HX status request can be used to
      determine which is which.
      
      Also note that we currently do not distinguish between the various HXN
      (G) types in the driver but that this may change eventually (e.g. when
      adding GPIO support).
