Subject: RDMA/bnxt_re: Use IS_ERR_OR_NULL where appropriate
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=374cb8610ac15737acb65ca0293c21dc2205662b;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

RDMA/bnxt_re: Use IS_ERR_OR_NULL where appropriate

Constructs such as if (ptr && !IS_ERR(ptr)) can be shorted to
just !IS_ERR_OR_NULL(ptr) instead.  Make substitutions in the bnxt_re
driver where appropriate.
