Takashi Iwai fb05e983ea ALSA: rawmidi: Access runtime->avail always in spinlock ... commit 88a06d6fd6 upstream. The runtime->avail field may be accessed concurrently while some places refer to it without taking the runtime->lock spinlock, as detected by KCSAN. Usually this isn't a big problem, but for consistency and safety, we should take the spinlock at each place referencing this field.
