Public bug reported:
[Impact]
KASAN detected a use-after-free condition, which could lead to memory
corruption or a crash.
[Test Case]
Rebuild kernel w/ CONFIG_KASAN=y, look for errors in dmesg.
[Fix]
3a39a12ad364a net: hns: fix KASAN: use-after-free in hns_nic_net_xmit_hw()
[Regression Risk]
Fix is restricted to the hns driver, which is the driver for the nics on the
Hi1616 SoC. Regressions would therefore be limited to platforms using this SoC,
such as the HiSilicon D05 board.
