[Lorenzo Bianconi]

Fix a possible deadlock in mtk_wed_attach if mtk_wed_wo_init routine fails.
Check wo pointer is properly allocated before running mtk_wed_wo_reset() and
mtk_wed_wo_deinit().

Changes sice v2:
- add WARN_ON in mtk_wed_mcu_msg_update()
- split in two patches
Changes since v1:
- move wo pointer checks in __mtk_wed_detach()

Lorenzo Bianconi (2):
  net: ethernet: mtk_wed: fix some possible NULL pointer dereferences
  net: ethernet: mtk_wed: fix possible deadlock if mtk_wed_wo_init fails
