Yes I have seen it but it has to wait now. I plan to send that as a fix
as part of 4.4-rcx fixes.

Santosh,

Not sure what the reason is. Can't this be sent to linux-next as should 
be the case if something is broken on that branch AFAIK. For us, this 
would help to merge to ti kernel based on 4.1.y if this is already part 
of an upstream branch. Otherwise, I will have to wait merge of the qmss 
accumulator series to ti kernel until this one is merged to upstream 
which will block the release. So I prefer you send this one to 
linux-next sooner than late.

Thanks and regards,

Murali

Ahh... You request was for linux-next. Thats no problem. My response was
when I plan to send that for upstream merge and that will be as part of 
the 4.4-rcx fixes.

Will add in my queue so that it will start showing up in linux-next
soon.

Santosh
