commit bc1a7f75c85e226e82f183d30d75c357f92b6029 upstream.
DMA with zero-length transfers doesn't make sense and this HW doesn't
support them at all, so increase the threshold.
Fixes: fc66b39fe36a ("i2c: mediatek: Use DMA safe buffers for i2c transactions")

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.
