Stupid small issues that I have found:
Bluetooth is spotty without this patch, that adds support for this specific chipset to the driver, especially with audio:
Wifi has issues sometimes on network switch, where it only returns -12 to wpa_supplicant, and you cant scan networks, or connect to networks, without unloading module(If built that way), or rebooting.
Left joycon not getting power when connected to console, so it dies while playing, but the right joycon reports that it is still 100% in horizon, where the left is completly dead. Seems weird, as I never had battery drain issues on the left joycon using the failoverflow kernel.
Battery desync fix should be added, even though hekate fixes this automatically, we dont all use hekate to launch linux, or CFW, I use argon-nx, which doesnt implement this fix, and neither does any cfw launcher. The SDHCI patch should be added as well, but changed so people can choose to enable it in menuconfig, if needed. I know that samsung evo 128gb cards dont boot without this patch.
Other than that, there are some updates to the XUDC patches, since this was put together, and frequency scaling patches on the tegra patchwork, that would be nice to be seen added to this kernel.
