The blink counter A was always selected because 0 was forced in the blink select counter register. The variable 'set' was obviously there to be used as the register value, selecting the B counter when id==1 and A counter when id==0. Tested on clearfog-pro (Marvell 88F6828) Signed-off-by: Richard Genoud <redacted>Looks good for me: Reviewed-by: Gregory CLEMENT <redacted> I thinks this one should go to v4.12-rc as it is a fix. As I modified the same part of the code in my series, I think I will have to rebase my series on top of this patch as soon as Linus Walleij will have accepted it.
I think we could also add:
