Subject: [PATCH for-rc 4/4] RDMA/erdma: Defer probing if netdevice can not be found
Date: Mon, 20 Mar 2023 16:46:52 +0800 [thread overview]
Message-ID: <20230320084652.16807-5-chengyou@linux.alibaba.com> (raw)
In-Reply-To: <20230320084652.16807-1-chengyou@linux.alibaba.com>
ERDMA device may be probed before its associated netdevice, returning
-EPROBE_DEFER allows OS try to probe erdma device later.
Fixes: d55e6fb4803c ("RDMA/erdma: Add the erdma module")
