Subject: [PATCH] net/hinic: fix crash in secondary process
[ upstream commit 4c670dfaa417bc5604c9c58b505a74e2725acdb2 ]
Some apps, such as fstack, will use secondary process to access the
memory of eth_dev_ops, and they want to get the info of dev, but hinic
driver does not initialized it when in secondary process.
Fixes: 66f64dd6dc86 ("net/hinic: fix secondary process")
