pwm: Set class for exported channels in sysfs
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.
