[PATCH 5.10 174/202] mtd: rawnand: qcom: Unmap the right resource upon probe failure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-stable review patch.  If anyone has any objections, please let me know.

------------------

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.

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