[PATCH v3] Bluetooth: btusb: mediatek: Avoid btusb_mtk_claim_iso_intf() NULL deref

[incogcyberpunk at proton.me]

Hi, 

Don't want to add trouble, just out of curiosity.

What is normally the route for patches to get into the mainline kernel? 

Isn't it as follows , as suggested in the documentations ? 
subsystem -> -next -> mainline -> stable ? 

What's this net tree , and how are the patches cherrypicked onto the  mainline kernel? is there a certain process?
