Subject: [PATCH v2] mtd: rawnand: atmel: Fix dma_mapping_error() address
Date: Wed,  2 Jul 2025 08:45:11 +0200	[thread overview]
Message-ID: <20250702064515.18145-2-fourier.thomas@gmail.com> (raw)

It seems like what was intended is to test if the dma_map of the
previous line failed but the wrong dma address was passed.

Fixes: f88fc122cc34 ("mtd: nand: Cleanup/rework the atmel_nand driver")
Signed-off-by: Thomas Fourier <fourier.thomas@gmail.com>
---
v1 -> v2:
- Add stable@vger.kernel.org
- Fix subject prefix
