Subject: RDMA/core: Remove unused ib_resize_cq() implementation
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6c45efd8f9bb8813524c3b8f904989af448bdd72;p=thirdparty%2Fkernel%2Fstable.git

RDMA/core: Remove unused ib_resize_cq() implementation

There are no in-kernel users of the CQ resize functionality, so drop it.
