Since commitabf4923e97("i2c: mediatek: disable zero-length transfers for mt8183"), there is a NULL pointer dereference for all the SoCs that don't have any quirk. mtk_i2c_functionality is not checking that the quirks pointer is not NULL before starting to use it. This commit add a call to i2c_check_quirks which will check whether the quirks pointer is set, and if so will check if the IP has the NO_ZERO_LEN quirk.

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.
