I guess so too.

Here you go.

@Boris do you want to add your Signed-off-by too?

@Bart please apply this patch.

Subject: ide-tape: Buildfix when IDETAPE_DEBUG_LOG is set to 1.

The format specifier for rq->sector didn't specify the proper size and
signedness. Borislav Petkov discovered that the signedness for
rq->nr_sectors and rq->current_nr_sectors also were incorrect.
