Subject: mtd: rawnand: qcom: Unmap the right resource upon probe failure
From: Bibek Kumar Patro <quic_bibekkum@xxxxxxxxxxx>
commit 5279f4a9eed3ee7d222b76511ea7a22c89e7eefd upstream.
We currently provide the physical address of the DMA region
rather than the output of dma_map_resource() which is obviously wrong.
