Hello, I was investigating why CPU hangs during of GPIO driver suspend and in the end it turned out that it is a Broadcom WiFi driver problem because it keeps OOB wake-interrupt enabled while WLAN interface is DOWN and this may cause a bit weird CPU hang on writing to INT_ENB register during of GPIO driver suspend. Meanwhile I also noticed that a few things could be improved in the driver, that's what this small series addresses.
