From: Colin Ian King <colin.k...@canonical.com>
The position index in leq_seq_next is not updated when the next
entry is fetched an no more entries are available. This causes
seq_file to report the following error:
"seq_file: buggy .next function lec_seq_next [lec] did not update
position index"
Fix this by always updating the position index.
[ Note: this is an ancient 2002 bug, the sha is from the
tglx/history repo ]
Fixes 4aea2cbff417 ("[ATM]: Move lan seq_file ops to lec.c [1/3]")
