commitb9ddd50911upstream. The max9611 driver reads the die temperature at probe time to validate the communication channel. Use the actual read value to perform the test instead of the read function return value, which was mistakenly used so far. The temperature reading test was only successful because the 0 return value is in the range of supported temperatures.

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.
