Hi,

while testing linux-next I wanted to reactivate the backlight type patches laying in my build-dir.

Within 2.6.36-rcX cycle I had successfully tested the backlight type patch [1] with an additional patch for radeon by Michel (posted to dri-devel ML, see [2]).

The main patch needs a little refreshing.

v2: drivers/platform/x86/asus-laptop.c: Refreshed to fit linux-next (next-20101027)

Kind Regards,

Hi,

I think rfkill has the same problem, on some platforms, the platform driver will add a rfkill switch, but the network (wlan/wimax/whatever) driver may also add one. AFAIK, the platform one is more likely to be able to power down the device completly.

Agreed your point! x86/laptop or wmi driver borrow rfkill interface for power control but confuse with userland applications.

Thank's Joey Lee
