audio_device: enforce the documented FIFO minimum in the EP-IN flow-control guard

2026-08-04T19:09:20Z

The comment above audiod_tx_packet_size() states flow control needs a FIFO of at least 4*Navg, but the guard tests nominal_size[1] <= fifo_depth * 4 - true for any FIFO larger than a quarter packet - instead of nominal_size[1] * 4 <= fifo_depth. As written, flow control engages on FIFOs far below its own documented minimum, where the depth/2 setpoint sits within one packet of empty and the packet_size = 0 branch (a zero-length packet, i.e. an audible 1 ms dropout for audio-class hosts) is reachable from ordinary scheduling jitter rather than only from gross clock deviation. With the guard corrected, undersized FIFOs fall back to the plain min(count, max) path as intended.

* license: use SPDX identifiers for src/ headers Replace the full ~20-line MIT license boilerplate on every src/ file with a two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500 lines of duplicated boilerplate.
