[ Upstream commit 6c7103aa026094a4ee2c2708ec6977a6dfc5331d ] When runtime is not enabled, pm_runtime_get_sync() returns -EACCESS, the counter will be incremented but the resume callback not called, so enumeration and charging will not start properly. To avoid that happen, disable irq on suspend and recheck on resume. Practically this happens when the device is woken up from suspend by plugging in usb.

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.
