If anyone has any objections, please let me know. ------------------ From: Brian Norris commit 8eef7d70f7c6772c3490f410ee2bceab3b543fa1 upstream. We are completely discarding the earlier value of 'bitflips', which could reflect a bitflip found in ubi_io_read_vid_hdr(). Let's use the bitwise OR of header and data 'bitflip' statuses instead.
