   3 Subject: [PATCH] Revert "mtd: spi-nor: fix Spansion regressions (aliased with
   4  Winbond)"
   5
   6 This reverts commit 67b9bcd36906e12a15ffec19463afbbd6a41660e.
   7
   8 The underlying issue breaking Spansion flash has been fixed with "mtd: spi-nor:
   9 wait until lock/unlock operations are ready" and "mtd: spi-nor: wait for SR_WIP
  10 to clear on initial unlock", so we can support unlocking for Winbond flash
  11 again.
