Many drivers create additional driver-specific device attributes when binding to the device, and providing managed version of device_create_group() will simplify unbinding and error handling in probe path for such drivers. Without managed version driver writers either have to mix manual and managed resources, which is prone to errors, or open-code this function by providing a wrapper to device_add_group() and use it with devm_add_action() or devm_add_action_or_reset().

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.
