5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: Yonglong Liu <liuyonglong@xxxxxxxxxx>
[ Upstream commit dbd2f3b20c6ae425665b6975d766e3653d453e73 ]
When a VF is calling hns3_init_mac_addr(), get_mac_addr() may
return fail, then the value of mac_addr_temp is not initialized.
Fixes: 76ad4f0ee747 ("net: hns3: Add support of HNS3 Ethernet Driver for hip08 SoC")
