Subject: [PATCH 1/2] mtd: spi-nor: fix spi_nor_lock_and_prep() usage
Date: Tue, 7 Jan 2020 23:23:16 +0100 [thread overview]
Message-ID: <20200107222317.3527-1-michael@walle.cc> (raw)
lock_and_prep() and unlock_and_unprep() are asymmetrical. The second
argument should be the same and represents the operation. This was
correct before commit 8cc7f33aadc8 ("mtd: spi-nor: factor out
replace-able flash_{lock,unlock}").
Fixes: 8cc7f33aadc8 ("mtd: spi-nor: factor out replace-able flash_{lock,unlock}")
