      USB: ftdi_sio: add support for FT-X series devices · dc0827c1
      Jim Paris authored
      Add PID 0x6015, corresponding to the new series of FT-X chips
      (FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X).  They all
      appear as serial devices, and seem indistinguishable except for the
      default product string stored in their EEPROM.  The baudrate
      generation matches FT232RL devices.
      
      Tested with a FT201X and FT230X at various baudrates (100 - 3000000).
      
      Sample dmesg:

      USB: serial: mos7840: Fixed MCS7820 device attach problem · 093ea2d3
      Donald Lee authored
      A MCS7820 device supports two serial ports and a MCS7840 device supports
      four serial ports. Both devices use the same driver, but the attach function
      in driver was unable to correctly handle the port numbers for MCS7820
      device. This problem has been fixed in this patch and this fix has been
      verified on x86 Linux kernel 3.2.9 with both MCS7820 and MCS7840 devices.

      memcg: revert fix to mapcount check for this release · be22aece
      Hugh Dickins authored
      Respectfully revert commit e6ca7b89 "memcg: fix mapcount check
      in move charge code for anonymous page" for the 3.3 release, so that
      it behaves exactly like releases 2.6.35 through 3.2 in this respect.
      
      Horiguchi-san's commit is correct in itself, 1 makes much more sense
      than 2 in that check; but it does not go far enough - swapcount
      should be considered too - if we really want such a check at all.
      
      We appear to have reached agreement now, and expect that 3.4 will
      remove the mapcount check, but had better not make 3.3 different.

      net: qmi_wwan: add Gobi and Pantech UML290 device IDs · b086cf04
      Bjørn Mork authored
      Adding the Pantech UML290 and all non-QDL Gobi device IDs from the
      qcserial driver now that we have support for shared net/QMI USB
      interfaces.  Most of these are not yet tested with this driver, but
      should be mostly identical to tested devices, except for device IDs.
      
      Gobi devices provide several different interfaces (serial/net/other)
      using the exact same class, subclass and protocol values.  This driver
      will only support the net/QMI function while there are other drivers
      supporting other device functions. The net/QMI interface number may
      also differ from device to device.  It has been noted that all the
      other interfaces have additional functional descriptors, so we use that
      to detect the interface supported by this driver.
