Subject: RDMA/bnxt_re: Clean up uverbs CQ creation path
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=2f49e159034478af3b5e3ab761066cb876e48343;p=thirdparty%2Flinux.git

RDMA/bnxt_re: Clean up uverbs CQ creation path

Remove unnecessary checks, user‑visible prints that can flood dmesg,
superfluous assignments, and convoluted goto label.
