This is not a correct change.
The checkpatch message said "generally".
You still have to verify the code.

It's not the same logic.
It would be if the code was:
while (end_of_queue_search(phead, plist) == false) {
pnextrframe = LIST_CONTAINOR(plist, union recv_frame, u);
pnextattrib = &pnextrframe->u.hdr.attrib;
if (SN_LESS(pnextattrib->seq_num, pattrib->seq_num)) {
plist = plist->next;
continue;
} else if (SN_EQUAL(pnextattrib->seq_num, pattrib->seq_num)) {
return false;
}
break;
}
But that's not necessary.
