I am sorry, if you got some of the mails twice. It seems there was a combination of bad timing and filling of my email box (some emails was sent OK, some seemed to be sent OK, but not and some was not sent at all). And I had list of mails from the patchset version 2, MFD/LEDs subsystem relevant patch is only:

	ARM: pxa: magician: Remove pdata for pasic3-leds

On the other hand if you got only a part of the patchset and you want to see missing parts, mail me and I will send you.

Best regards,
