      can: Fix possible NULL pointer dereference in ems_usb.c · 1c0b28b1
      Hans J. Koch authored
      In ems_usb_probe(), a pointer is dereferenced after making sure it is NULL...
      
      This patch replaces netdev->dev.parent with &intf->dev in dev_err() calls to
      avoid this.

      ipv6: Fix tcp_v6_send_response transport header setting. · 6651ffc8
      Herbert Xu authored
      My recent patch to remove the open-coded checksum sequence in
      tcp_v6_send_response broke it as we did not set the transport
      header pointer on the new packet.
      
      Actually, there is code there trying to set the transport
      header properly, but it sets it for the wrong skb ('skb'
      instead of 'buff').
      
      This bug was introduced by commit
      a8fdf2b3 ("ipv6: Fix
      tcp_v6_send_response(): it didn't set skb transport header")
