From 76a4707de5e18dc32d9cb4e990686140c5664a15 Mon Sep 17 00:00:00 2001
From: Brian Norris <computersforpeace@gmail.com>
Date: Fri, 29 Jan 2016 11:25:35 -0800
Subject: [PATCH] mtd: spi-nor: add SPI_NOR_HAS_LOCK flag
We can't determine this purely by manufacturer type (see commit
67b9bcd36906 ("mtd: spi-nor: fix Spansion regressions (aliased with
Winbond)")), and it's not autodetectable by anything like SFDP. So make
a new flag for it.
