Subject[PATCH AUTOSEL 5.4 134/350] net: hns3: log and clear hardware error after reset complete
Date
From: Jian Shen <shenjian15@huawei.com>

[ Upstream commit 4fdd0bca6152aa201898454e63cbb255a18ae6e9 ]

When device is resetting, the CMDQ service may be stopped until
reset completed. If a new RAS error occurs at this moment, it
will no be able to clear the RAS source. This patch fixes it
by clear the RAS source after reset complete.
