All 3 patches look good to me.
For easier patch management, next time it would be good
to send all three as replies to an introductory message,

Also, please use "Signed-off-by:" rather than "Signed-off by:".
Besides the fact that checkpatch warns about that I'm not sure
it gets tracked properly...
I'll fix that before committing.

Thanks!
