[ Upstream commit aafced673c06b7c77040c1df42e2e965be5d0376 ] The i2c driver default do dma reset after i2c reset, but sometimes i2c reset will trigger dma tx2rx, then apdma write data to dram which has been i2c_put_dma_safe_msg_buf(kfree). Move dma reset before i2c reset in mtk_i2c_init_hw to fix it.

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.
