ide-tape: struct idetape_tape_t: remove unused members
- last_frame_position: only being written to once - firmware_revision, product_id, vendor_id: used once, remove from struct idetape_tape_t and deal with them locally - firmware_revision_num: only written to once - tape_still_time_begin: completely unused - tape_still_time: never written to; remove corresponding code chunk - uncontrolled_last_pipeline_head: only once written to - blocks_in_buffer: only written to Signed-off-by: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
