Subject[PATCH 5.4 056/109] RDMA/siw: Fix reporting vendor_part_id
Date
From: Kamal Heib <kamalheib1@gmail.com>

[ Upstream commit 04340645f69ab7abb6f9052688a60f0213b3f79c ]

Move the initialization of the vendor_part_id to be before calling
ib_register_device(), this is needed because the query_device() callback
is called from the context of ib_register_device() before initializing the
vendor_part_id, so the reported value is wrong.

Fixes: bdcf26bf9b3a ("rdma/siw: network and RDMA core interface")
