Subject: [PATCH 4.4 098/312] mtd: nand: fix ONFI parameter page layout

From: Boris Brezillon <boris.brezillon@...e-electrons.com>

commit de64aa9ec129ba627634088f662a4d09e356ddb6 upstream.

src_ssync_features field is only 1 byte large, and the 4th reserved area
is actually 8 bytes large.

Fixes: d1e1f4e42b5 ("mtd: nand: add support for reading ONFI parameters from NAND device")
