The pointer() callback gets its value by reading the I2S BYTE_COUNT register. This is a 64-bit runnning transaction counter. If a transaction was aborted in the middle of a sample buffer, the counter will stop counting on a number divisible by the buffer size. Since we actually use it as a pointer into an aligned buffer, however, we do want to ensure that it always starts at a number divisible by the buffer size when starting a transaction, hence we reset it whenever starting a transaction. To accomplish this, it wasn't necessary to zero bytescount at the termination of each transaction, so remove this unnecessary code.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
