-Subject: [PATCH] Revert "mtd: spi-nor: disable protection for Winbond flash at
- startup"
-
-This reverts commit c6fc2171b249e73745c497b578b417a2946f1b2f.
-
-This commit is breaking read access on at least s25fl064k, but also
-possibly other Spansion flash chips.
-
-Any mtd read seems to succeed, but simply returns a zero-filled buffer.
