Subject: RDMA/bnxt_re: Create direct symbol link between bnxt modules
X-Git-Tag: v5.15~1220^2~20
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=bcf9ee0520fa95c692eaf6ec5e61e55059c75e15;p=platform%2Fkernel%2Flinux-starfive.git

RDMA/bnxt_re: Create direct symbol link between bnxt modules

Convert indirect probe call to its direct equivalent to create a symbol
link between RDMA and netdev modules. This will give us an ability to
remove custom module reference counting that doesn't belong to the driver.
