I'm appplying patches 1-3 and got a checkpatch warning for each patch:

  WARNING: Unexpected content after email: 'Heiko Stuebner <heiko@...ech.de> on rk3588', should be: 'Heiko Stuebner <heiko@...ech.de> (on rk3588)'

I'm fixing it while applying those 3 patches.

Damon, can you fix that for the remaining patches before sending a new
iteration?

Luca
