fixes: commit 62116e51 mtd: nand: omap2: Support for hardware BCH error correction. In omap_elm_correct_data(), if bitflip_count in an erased-page is within the correctable limit (< ecc.strength), then it is not indicated back to the caller ecc->read_page(). This mis-guides upper layers like MTD and UBIFS layer to assume erased-page as perfectly clean and use it for writing even if actual bitflip_count was dangerously high (bitflip_count > mtd->bitflip_threshold). This patch fixes this above issue, by returning 'stats' to caller ecc->read_page() under all scenarios. Reported-by:
