2019-12-18brcmfmac: Keep OOB wake-interrupt disabled when it shouldn't be enabledDmitry Osipenko
NVIDIA Tegra SoCs do not like when OOB wake is enabled and WiFi interface is in DOWN state during suspend. This results in a CPU hang on programming OOB wake-up state of the GPIO controller during of system's suspend. The solution is trivial: don't enable wake for the OOB interrupt when it should be disabled. This fixes hang on Tegra20 (Acer A500) and Tegra30 (Nexus 7) devices which are using BCM4329 and BCM4330 WiFi chips respectively.

2019-12-18rsi: add missing endpoint sanity checksJohan Hovold
The driver expects at least one bulk-in endpoint when in "wifi-alone" operating mode and two bulk-in endpoints otherwise, and would otherwise fail to to submit the corresponding bulk URB to the default pipe during probe with a somewhat cryptic message: rsi_91x: rsi_rx_urb_submit: Failed in urb submission rsi_91x: rsi_probe: Failed in probe...Exiting RSI-USB WLAN: probe of 2-2.4:1.0 failed with error -8 The current endpoint sanity check looks broken and would only bail out early if there was no bulk-in endpoint but at least one bulk-out endpoint. Tighten this check to always require at least one bulk-in and one bulk-out endpoint, and add the missing sanity check for a Bluetooth bulk-in endpoint when in a BT operating mode.

To minimize the changes in a given step, the input descriptor information is left as as a byte array (u8 *), even though it should be a little-endian word array (__le32 *). That will be changed in the next patch. Several places where checkpatch.pl complains about a space after a cast and other warnings are fixed.
