Alok TiwariandGreg Kroah-Hartman ca3e48e968 scsi: ufs: mcq: Fix memory allocation checks for SQE and CQE ...

[ Upstream commit 5cb782ff3c ]

Previous checks incorrectly tested the DMA addresses (dma_handle) for
NULL. Since dma_alloc_coherent() returns the CPU (virtual) address, the
NULL check should be performed on the *_base_addr pointer to correctly
detect allocation failures.

Update the checks to validate sqe_base_addr and cqe_base_addr instead of
sqe_dma_addr and cqe_dma_addr.
