If anyone has any objections, please let me know. ------------------ From: Leon Romanovsky [ Upstream commit 8e17e101e04a3dc062e2719da57ff78c1c060632 ] hfi1_init_dd() allocates the shared AIP/VNIC RX support before returning. If hfi1_init() or hfi1_register_ib_device() later fails, init_one() tears down the device data without calling hfi1_free_rx(). This leaks netdev_rx and its dummy netdev. Free the RX support after IB unregistration and before postinit_cleanup(), as done on normal device removal.
