[PATCH v3] mtd: rawnand: qcom: unmap dma address during probe failure

From: Bibek Kumar Patro
Date: Tue Sep 12 2023 - 06:19:48 EST


Fix address argument of nand controller currently being
passed to dma_unmap_resource() in probe error path.
This address argument should be the dma address returned by
dma_map_resource() instead of the physical address of nand controller.

Fixes: 7330fc505af4 ("mtd: rawnand: qcom: stop using phys_to_dma()")
