Hi Greg,
If this patch is ok, can we please have it in v4.6 .
Anyway, the problem patch which this patch tried to fix has already
been reverted by Linus -
1701f680407c ("Revert "ppdev: use new parport device model"") but we still
can have problem with the other devices that use parport.
BTW, I know you are busy, but in these situations where I need to have
the fix urgently in the tree, is there any other way to solve the purpose?
I feel it was incompetency on my part where Linus had to interfere and
revert a patch even though the fix was already posted.
regards
sudip
