Document the fact that the autosuspend delay and enable helpers may change the power.usage_count and resume or suspend a device depending on the values of power.autosuspend_delay and power.use_autosuspend. Note that this means that a driver must disable autosuspend before disabling runtime pm on probe errors and on driver unbind if the device is to be suspended upon return (as a negative delay may otherwise keep the device resumed).

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.
