Subject: RDMA/ocrdma: Fix memory leak in _ocrdma_alloc_pd()
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=18eaf1f1959add9bbbfa5442fc5d9b59f7d4e1bd;p=linux-beck.git

RDMA/ocrdma: Fix memory leak in _ocrdma_alloc_pd()

If ocrdma_get_pd_num() fails, then we need to free the pd struct we allocated.

This was detected by Coverity (CID 1271245).
