4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Boris Brezillon <boris.brezil...@bootlin.com>
commit d098093ba06eb032057d1aca1c2e45889e099d00 upstream.
nanddev_neraseblocks() currently returns the number pages per LUN
instead of the total number of eraseblocks.
Fixes: 9c3736a3de21 ("mtd: nand: Add core infrastructure to deal with NAND
devices")
