net: atm: fix update of position index in lec_seq_next
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]") Signed-off-by: Colin Ian King <colin.king@canonical.com> Link: https://lore.kernel.org/r/20201027114925.21843-1-colin.king@canonical.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
