Booting Linux on a mx6q based board leads to the following warning: (NULL device *): hwmon_device_register() is deprecated. Please convert the driver to use hwmon_device_register_with_info(). , so do the conversion as suggested. Also, this results in the core taking care of creating the 'name' attribute, so drop the code doing that from the thermal driver. The initial attempt to convert this driver to hwmon_device_register_with_info() caused issues on the N900 platform in commit7611fb6806("thermal: thermal_hwmon: Convert to hwmon_device_register_with_info()"): bq27xxx-battery 2-0055: failed to register battery bq27xxx-battery: probe of 2-0055 failed with error -22 ... rx51-battery: probe of n900-battery failed with error -22 , leading to a revert in commit3feb479cea("Revert "thermal: thermal_hwmon: Convert to hwmon_device_register_with_info()""). The probe errors happened due to the '-' character being present in the name of the power supply devices: bq27200-0 and rx51-battery. Since commit74d3b64197("hwmon: Relax name attribute validation for new APIs") hwmon will no longer treat these names as errors, allowing the transition for hwmon_device_register_with_info() to happen in a safely manner.

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.
