Subject: [PATCH 4.19 1/8] Revert "mtd: spinand: Fix OOB read"
Date: Thu, 7 Jan 2021 15:32:01 +0100 [thread overview]
Message-ID: <20210107143047.732584985@linuxfoundation.org> (raw)
In-Reply-To: <20210107143047.586006010@linuxfoundation.org>
From: Felix Fietkau <nbd@nbd.name>
This reverts stable commit baad618d078c857f99cc286ea249e9629159901f.
This commit is adding lines to spinand_write_to_cache_op, wheras the upstream
commit 868cbe2a6dcee451bd8f87cbbb2a73cf463b57e5 that this was supposed to
backport was touching spinand_read_from_cache_op.
It causes a crash on writing OOB data by attempting to write to read-only
kernel memory.
