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