- Subject: [PATCH] brcmfmac: restore bus state when enter_D3 fails
- In brcmf_pcie_suspend() we inform the firmware on the device that
- it will enter in D3 state. Before this is done we already bring down
- the bus state. However, When entering D3 fails we abort the suspend
- and the bus state need to be restored.
