net: wwan: mhi: fix memory leak in mhi_mbim_dellink

Browse source

[ Upstream commit 668205b9c9 ]

MHI driver registers network device without setting the
needs_free_netdev flag, and does NOT call free_netdev() when
unregisters network device, which causes a memory leak.

This patch sets needs_free_netdev to true when registers
network device, which makes netdev subsystem call free_netdev()
automatically after unregister_netdevice().
