To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.
To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].
This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

This looks like a purely net-next change, and we are in the merge
window: net-next is closed for the time being. Could you please re-post
after net-next re-open?
Additionally, I suggest you to bundle the net-next patches in a single
series, namely:
bnx2x: replace usage of found with dedicated list iterator variable
octeontx2-pf: replace usage of found with dedicated list iterator variable
sctp: replace usage of found with dedicated list iterator variable
taprio: replace usage of found with dedicated list iterator variable
that will simplify the processing, thanks!
Paolo

Thanks for letting me know, I'll re-post after net-next is reopened.

Are you saying having a single patchset for all /net and /drivers/net
related changes? This would also simplify a lot on my end.
