Subject: mwifiex: fix PCIe hs_cfg cancel cmd timeout
From: Bing Zhao <bzhao@xxxxxxxxxxx>
commit b7be1522def9a9988b67afd0be999c50a96394b5 upstream.
For pcie8897, the hs_cfg cancel command (0xe5) times out when host
comes out of suspend. This is caused by an incompleted host sleep
handshake between driver and firmware.
Like SDIO interface, PCIe also needs to go through firmware power
save events to complete the handshake for host sleep configuration.
Only USB interface doesn't require power save events for hs_cfg.
