class/audio: drop redundant clear_stall busy-clear workaround in set_interface

2026-07-03T03:06:48Z

audiod_set_interface used usbd_edpt_clear_stall() on a non-stalled endpoint purely to drop a leftover BUSY bit ('THIS IS A WORKAROUND!'), from when ep_close() did not clear endpoint state. That premise no longer holds: by the time the workaround ran, the endpoint's ep_status (incl. BUSY) had already been zeroed - by usbd_edpt_close() on close-API ports (ip3511, rusb2) or by usbd_edpt_iso_activate() on iso-alloc ports - so the call was dead code. Verified: full audio_test capture works across stop/start streaming (arecord start -> stop -> restart, each delivering a complete buffer) on stm32f407disco (dwc2, working iso); 25 raw SET_INTERFACE alt1<->alt0 cycles leave the device responsive; behaviour is byte-identical with and without the workaround on metro_m4 (samd51, whose iso-IN stalls for a separate pre-existing reason); builds clean on iso-alloc (samd, dwc2) and close-API (lpc55, ra) ports.

license: use SPDX identifiers for src/ headers (#3749)

* 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.

class/audio: remove unused audio20_control_request_t

2026-06-18T09:36:05Z

After the UAC2 examples switched to tusb_control_request_t with TU_U16_HIGH/LOW() extraction, audio20_control_request_t is no longer referenced anywhere in the tree. It is a byte-overlay of the setup packet whose bChannelNumber/bControlSelector/bInterface/bEntityID sub-byte fields silently misread on big-endian once wValue/wIndex are converted to host order (tu_le16toh in dcd.h), so leaving it in the public header is a latent BE trap; the BE bitfield guard previously added to its bmRequestType_bit only masked that by guarding byte 0. Drop the struct entirely. Callers should use tusb_control_request_t and TU_U16_LOW/HIGH(wValue|wIndex), matching audio_device.c and the examples. Co-Authored-By: Claude Opus 4.8 (1M context)
