The "dma" variable of tegra_i2c_xfer_msg() function doesn't bring much in regards to readability and generation of the code. Besides readability, it's also not very nice that the is_curr_dma_xfer is initialized in tegra_i2c_xfer_msg() and then could be overridden by tegra_i2c_config_fifo_trig(). In a result, the "dma" variable creates slight confusion since it's not instantly obvious why it's set after tegra_i2c_config_fifo_trig(). Hence should be better to have the variable removed. This makes code more consistent.

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.
