Again, I do not like to take patches without any changelog text at all :(

Sorry, I added this after the "---" line. I thought it was this one the missing item:

V3 (Alessandro): fixed From line in patch, added alessandro's acked-by

V2 (Pat): added Tested-by and incorrect From line

V1 (Pat): picked from ohwr.org repo, where most fmc users pick from.

thanks

Ah, sorry, wrong "changelog". I meant the area that shows up in git about what this patch does. There's no description of it other than the Subject line. While this is a simple patch, it is always good to say something like "variable foo was set but never actually used, so it's safe to remove it as the function it called did not change the hardware state" or something like that.

thanks,

Yes. Ok, I'll add a longer commit message for V4 of the whole set. Tomorrow (/me leaving now to a client).
