Somebody in the thread at some point said:
| This patch adds a framebuffer notifier in order to detect
| FB_BLANK events and switch the JBT6K74 LCM controller into
| its power saving mode.
| This has the potential of saving something like 50mW during screen blank.
| + struct notifier_block fb_notif;
Thanks, that's educational, I never met it before; it certainly made for
a short patch. I sent it on stable.
The only thing I guess to be aware of is that this is disconnected from
/sys control of backlight device status unless I missed a point
somewhere, it means that framebuffer blanking is now better for power
than turning down backlight by /sys and should be preferred.
