Fixes: 60f36637bbbd ("wlcore: sdio: allow pm to handle sdio power")
Tested-by: John Stultz <john.stultz@xxxxxxxxxx>
Acked-by: John Stultz <john.stultz@xxxxxxxxxx>

Wei Xu: This also fixes a functional regression with wifi on the
HiKey960 board that was introduced in 4.18-rc with commit 60f36637bbbd
("wlcore: sdio: allow pm to handle sdio power").

Could you please be sure to queue this for the 4.18-rc too?
