Notifications for devices without bus or class set get dropped by dev_uevent_filter(). Adding the class to the exported child matches what the GPIO subsystem is doing. With this change exporting a channel triggers a udev event, which gives userspace a chance to fixup permissions and makes it possible for non-root users to make use of the PWM subsystem.

README
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.
