4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris Brezillon boris.brezillon@bootlin.com
commit b637ef779575a977068025f842ecd480a9671f3f upstream.
nand_jedec_detect() should return 1 when the PARAM page parsing succeeds, otherwise the core considers JEDEC detection failed and falls back to ID-based detection.
