Why isn't it relevant? You are using a LED driver, which already has a well-specified interface for interacting with userspace, why are you trying to create a new one? That will only break userspace tools and is not allowed. > 3.

Are you sure the existing user/kernel api can't handle this already? Are you wanting to do PWM with the LED to get it to change to different values somehow? If so, I think the existing interface can handle this today, right? Just set the different values in your driver beforehand. thanks, greg k-h -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
