commit b424315a287c70eeb5f920f84c92492bd2f5658e upstream. The TEMP0_CFG configuration register contains different field to set up the temperature controller. However in the code, nothing prevents a setup to overwrite the previous one: eg. writing the hdak value overwrites the sensor selection, the sensor selection overwrites the hdak value. In order to prevent such thing, use a regmap-like mechanism by reading the value before, set the corresponding bits and write the result.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
