-------------------------------------------
Raghu,
Thanks for looking at this patch, I guess I am wrong but in the way you
described.
!(true) && false => false == false then set it to true. That's ok you want to
let it true
!(false) && false => false == false then set it to true. That's not ok we want
it to stay false
!(false) && true => true != false then let it be false. That's not ok we want
it to be true
!(true) && true => false != true then let it be true. That's ok you want it
true
Also that value is reset in hsync to false.
So I indeed need to fix this thx!
