+From 76a4707de5e18dc32d9cb4e990686140c5664a15 Mon Sep 17 00:00:00 2001

+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.
