      Wei Yongjun authored
      Add missing platform_set_drvdata() in tps65217_charger_probe(), otherwise
      calling platform_get_drvdata() in remove returns NULL.
      
      This is detected by Coccinelle semantic patch.

      tipc: fix NULL pointer dereference in shutdown() · d2fbdf76

      tipc_msg_create() can return a NULL skb and if so, we shouldn't try to
      call tipc_node_xmit_skb() on it.

      I feel like we should maybe return -ENOMEM or -ENOBUFS, but I'm not sure
      userspace is equipped to handle that. Anyway, this is better than a GPF
      and looks somewhat consistent with other tipc_msg_create() callers.

      ====================
      hv_netvsc: fixes for VF removal path
      
      Kernel crash is reported after VF is removed and detached from netvsc
      device. Turns out we have multiple different (but related) issues on the
      VF removal path which I'm trying to address with PATCHes 2-5 of this
      series. PATCH1 is required to support the change.
      
      Changes since v1:
      - Re-arrange patches in the series to not introduce new issues [David Miller]
      - Add PATCH5 which fixes a new issue I discovered while testing.
      - Add Haiyang' A-b tags to PATCH1-4
      
      With regards to Stephen's suggestion: I believe that switching to using RCU
      and eliminating vf_use_cnt/vf_inject is the right thing to do long-term, we
      can either put this on top of this series or do it later in net-next.

      hv_netvsc: fix bonding devices check in netvsc_netdev_event() · 0dbff144
      Vitaly Kuznetsov authored
      Bonding driver sets IFF_BONDING on both master (the bonding device) and
      slave (the real NIC) devices and in netvsc_netdev_event() we want to skip
      master devices only. Currently, there is an uncertainty when a slave
      interface is removed: if bonding module comes first in netdev_chain it
      clears IFF_BONDING flag on the netdev and netvsc_netdev_event() correctly
      handles NETDEV_UNREGISTER event, but in case netvsc comes first on the
      chain it sees the device with IFF_BONDING still attached and skips it. As
      we still hold vf_netdev pointer to the device we crash on the next inject.
