The usage count function is based on ndev_running flag that is updated before calling ndo_open/close, but if ndo is called in another place, as with suspend/resume, the counter is not changed, that breaks sus/resume. For common resource no difference which device is using it, does matter only device count. So, replace usage count function on var and inc and dec it in ndo_open/close.

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.
