Subject: RDMA/bnxt_re: Remove some dead code
X-Git-Tag: v6.12~8^2~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=aceee63a3aba4611f89dfc7e127792f469f45526;p=platform%2Fkernel%2Flinux-amlogic.git

RDMA/bnxt_re: Remove some dead code

If the probe succeeds, then auxiliary_get_drvdata() can't return a NULL
pointer.

So several NULL checks can be removed to simplify code.
