Subject: [PATCH v2 4/6] mtd: spi-nor: cadence-quadspi: Fix error path on failure to acquire reset lines
Date: Tue, 26 May 2020 15:06:02 +0530	[thread overview]
Message-ID: <20200526093604.11846-5-vigneshr@ti.com> (raw)
In-Reply-To: <20200526093604.11846-1-vigneshr@ti.com>

Make sure to undo the prior changes done by the driver when exiting due
to failure to acquire reset lines.
