Subject: RDMA/ocrdma: Fix check for NULL instead of IS_ERR
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=55a8d62a3bd2a0536d526da817fd4f49e6470770;p=linux-beck.git

RDMA/ocrdma: Fix check for NULL instead of IS_ERR

The ocrdma_alloc_lkey() function never returns NULL pointers -- it
returns ERR_PTRs.
