BUG-09: Buffer partial 64-byte frame remainders across URB completions
to prevent silent data loss when USB bulk transfers return incomplete
chunks. Adds remainder and combined buffers to tascam_card struct.
BUG-10: Distinguish transient USB errors (-EOVERFLOW, -ENOENT, -EPIPE)
from fatal ones in capture completion. Resubmit URB on transient errors
instead of dropping it, preventing capture stream death on transient
USB bandwidth contention or controller glitches.
BUG-11: Return playback_frames_consumed from pointer callback during
ghost playback instead of always returning 0, providing correct
semantics when the callback is queried indirectly.
BUG-12: Unanchor MIDI output URB before returning on error path in
tascam_midi_out_complete to prevent the URB from remaining stuck in
the anchor's pending list.
- Add USB_PID_TASCAM_US200 (0x8034) product ID constant
- Introduce MODE_VAL_STREAM_START_US200 (0x0032) for device-specific stream mode
- Parameterize us144mkii_configure_device_for_rate() to accept stream_mode value
- Extend model naming logic to display "US-200" for US-200 devices
- Add US-200 to USB device ID table for automatic recognition
Fixed all coding style issues reported by checkpatch.pl.
This includes:
- Trailing statements on new lines.
- Added missing blank lines after declarations.
- Corrected indentation of switch/case statements and labels.
- Added comments for memory barriers.
- Removed unnecessary braces.
Added Kdocs to all public functions and data structures to
improve code documentation.
This commit includes:
- Reverted audio stream decoupling to restore original behavior.
- Implemented SysEx state machine and error retry for MIDI handling.
- Performed memory leak audit and confirmed no obvious leaks.
- Optimized playback and capture data copying for efficiency.
- Reordered `tascam_card` structure for improved cache locality.
- Fixed `active_urbs` counter management to prevent "URBs still active" errors.
