Hi Guenter,

By some reason, I obtained only this your mail as a reply to sent patchset V1
Later on, I discovered your comments at 
https://www.spinics.net/lists/platform-driver-x86/msg21412.html
And saw that you also have comments regarding [PATCH v1 3/4].
I'm resending patchset v2 that address your comments.

Thanks,
    Michael.
