Hi Pavel
As for " Please Cc LED drivers to the LED maintainers...", does it mean that I only need to Cc LED drivers to LED maintainers?
Or do I need to send this driver to linux-leds@...r.kernel.org instead of platform-driver-x86@...r.kernel.org.

Best regards
Yuechao Zhao

Please Cc LED drivers to the LED maintainers...

Please check CodingStyle, avoid useless comments and check word wrapping in your email settings.
