Subject: [PATCH] UBPORTS SAUCE: Disable 8723cs power saving
The runtime power management features in the 8723cs firmware on the
PinePhone don't seem to work correctly. While we expect the chipset to
leave a low power state when it's time to send or receive data, instead
we get a delay of 10-20 seconds before any packets are sent.
