clean up PVS-Studio static-analysis findings for raspberry_pi_pico

2026-06-11T23:34:30Z

Resolves all TinyUSB-owned alerts reported by the CI PVS-Studio job (static_analysis.yml, run with --security-related-issues) on the raspberry_pi_pico board: 0 remaining in src/ and examples/. Genuine fixes: - ncm_device: validate wNdpIndex against sizeof(nth16_t), not the pointer size sizeof(nth16) (4 bytes) — the latter under-checks the NTB header (V568). - tusb: drop the redundant `ff_buf != NULL && ff_bufsize > 0` guard in tu_edpt_stream_init(); the early return already guarantees it (V560). - midi_host: bounds-check idx in tuh_midi_itf_get_info() instead of the always-true `&_midi_host[idx]` pointer (V560). - examples: fully initialize resolutions_per_format / frame_num / interval_ms arrays instead of leaving trailing elements implicitly zero (V1009). False positives suppressed at the cause: - usbd/usbh: hide the weak dcd_deinit()/hcd_deinit() stubs from the analyzer with #ifndef PVS_STUDIO. PVS analyzes one TU at a time and binds the call to the always-false weak stub (it cannot model the linker selecting the port's strong definition), then reports the cleanup loop after TU_ASSERT(...deinit()) as unreachable (V779). False positives suppressed locally (inline //-V or .pvsconfig): - .pvsconfig: V501 (HID descriptor macros), V763 (rhport override), V785 (audio function-index switch), V1044 (hardware poll loops). - inline //-V for config-dependent or intentional constructs: V512, V514-style contiguous clears, V547, V557, V560, V614, V619, V641, V1008, V1037, V1048, V1086. Verified: all examples build for raspberry_pi_pico; ceedling test:all passes (60/60); re-run of the CI-exact PVS invocation reports zero TinyUSB-owned findings.

remove duplicated tu_le16toh since we have converted the endian when setup.
