[PATCH 4.20 028/145] mtd: rawnand: Fix JEDEC detection

[Greg Kroah-Hartman]

4.20-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris Brezillon <boris.brezillon@xxxxxxxxxxx>

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.

Fixes: 480139d9229e ("mtd: rawnand: get rid of the JEDEC parameter page in nand_chip")
