Subject: [PATCH rdma-next v2 2/5] RDMA/bnxt_re: Create direct symbolic link between bnxt modules
Date: Thu,  1 Apr 2021 09:57:12 +0300	[thread overview]
Message-ID: <20210401065715.565226-3-leon@kernel.org> (raw)
In-Reply-To: <20210401065715.565226-1-leon@kernel.org>

From: Leon Romanovsky <leonro@nvidia.com>

Convert indirect probe call to its direct equivalent to create
symbols 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.
