Subject: RDMA/hns: Fix mismatch exception rollback
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dc3bda6e568e9310b7cd07769dd70a3f0cd696ca;p=linux.git

RDMA/hns: Fix mismatch exception rollback

When dma_alloc_coherent() fails in hns_roce_alloc_hem(), just call
kfree() to release hem instead of hns_roce_free_hem().

Fixes: c00743cbf2b8 ("RDMA/hns: Simplify 'struct hns_roce_hem' allocation")
