      can: ti_hecc: fix oops during rmmod · ab04c8bd
      Marc Kleine-Budde 提交于
      This patch fixes an oops which occurs when unloading the driver, while the
      network interface is still up. The problem is that first the io mapping is
      teared own, then the CAN device is unregistered, resulting in accessing the
      hardware's iomem:

      can: janz-ican3: fix support for older hardware revisions · e21093ef
      Ira W. Snyder 提交于
      The Revision 1.0 Janz CMOD-IO Carrier Board does not have support for
      the reset registers. To support older hardware, the code is changed to
      use the hardware reset register on the Janz VMOD-ICAN3 hardware itself.

      at91ether: return PTR_ERR if call to clk_get fails · 3cfc1590
      Devendra Naga 提交于
      we are currently returning ENODEV, as the clk_get may give a exact
      error code in its returned pointer, assign it to the ret by using the
      PTR_ERR function, so that the subsequent goto label will jump to the
      error path and clean the driver and return the error correctly.

      net: qmi_wwan: adding Huawei E367, ZTE MF683 and Pantech P4200 · 9db273f4
      Bjørn Mork 提交于
      One of the modes of Huawei E367 has this QMI/wwan interface:
      
       I:* If#= 1 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=01 Prot=07 Driver=(none)
       E:  Ad=83(I) Atr=03(Int.) MxPS=  64 Ivl=2ms
       E:  Ad=84(I) Atr=02(Bulk) MxPS= 512 Ivl=0ms
       E:  Ad=02(O) Atr=02(Bulk) MxPS= 512 Ivl=4ms
      
      Huawei use subclass and protocol to identify vendor specific
      functions, so adding a new vendor rule for this combination.
      
      The Pantech devices UML290 (106c:3718) and P4200 (106c:3721) use
      the same subclass to identify the QMI/wwan function.  Replace the
      existing device specific UML290 entries with generic vendor matching,
      adding support for the Pantech P4200.
      
      The ZTE MF683 has 6 vendor specific interfaces, all using
      ff/ff/ff for cls/sub/prot.  Adding a match on interface #5 which
      is a QMI/wwan interface.
