Subject: [PATCH 2/2] mtd: spi-nor: fix locking argument in spi_nor_is_locked()
Date: Tue,  7 Jan 2020 23:23:17 +0100	[thread overview]
Message-ID: <20200107222317.3527-2-michael@walle.cc> (raw)
In-Reply-To: <20200107222317.3527-1-michael@walle.cc>

The second argument represents the operation which takes the lock. Add a
new SPI_NOR_OPS_IS_LOCKED and use it.

Fixes: 5bf0e69b67a5 ("mtd: spi-nor: add mtd_is_locked() support")
