The cal_dmaqueue structure only contains the list of queued buffers. Move the other fields that are logically related to the DMA queue (current and next buffer points, state, wait queue and lock) from cal_ctx to cal_dmaqueue. Take this as an opportunity to document the fields usage and to give them more appropriate names. The 'active' field stored the list of all queued buffers, not the active buffers, so rename it to 'queue'. The 'cur_frm' and 'next_frm' are respectively renamed to 'active' and 'pending' to better explain their purpose. The 'dma_state' and 'dma_wait' fields are stripped of their 'dma_' prefix as they're now part of cal_dmaqueue. Finally, 'slock' is renamed to 'lock'.

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 Restructured Text 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.
