This patch adds the full audio capture data path. It allocates and manages bulk URBs to receive audio data from the device. The incoming data is in a custom multiplexed format. A workqueue is used to offload the decoding process from the interrupt context. The `capture_urb_complete` handler copies raw data into a ring buffer and schedules the work. The `tascam_capture_work_handler` then reads from this buffer, decodes the data into standard S32_LE samples, and copies it to the ALSA capture buffer. The PCM trigger is updated to manage the submission of capture URBs, and the feedback handler now also advances the capture stream pointer to keep it synchronized with playback.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
