I noticed that pwm/sysfs.c doesn't seem to notify user space after a channel has been exported through the sysfs interface. This does e.g. happen with gpio/gpiolib-sysfs.c, and allows udev to jump in and change permissions of newly exported PWM channels. (This seems racy, but I believe this is the best way to do it right now..)
Before I start familiarizing myself with the linux driver model: would you be open to changing the current behavior? (I believe device_create_with_groups() vs device_create() & device_register() is what's causing this, but I don't yet know the implications of using one over the other.)
