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).
