--- Comment #146 from Dennis Jansen <[email protected]> ---
Thanks Kieran!

I've tested whether 20 cycles are sufficient on my system and... they are for
me. I get to a maximum of 9. 

I've modified the patch by Kieran 
- to change the ec_reset function into a void and 
- to show the number of loops. This way we can do some debugging on that number
of 20 loops
- to warn if all loops are used up. On such systems there may be need to
increase the number of loops.

I think it might be hard to get the patch in for *all* Samsung systems. We
should probably try to collect the concrete systems (535,530,900) and restrict
the fix to these systems. My system is
535U3C / NP535U3C-A04DE
(sudo dmidecode | grep Product)

But as there may be more affected systems - also non-Samsung systems, should we
try to create a boot parameter which activates the EC clearing as well?

Attaching patch next.
