From: Jie Wang <wangjie125@xxxxxxxxxx>
commit 2a21dab594a98c338c4bfbc31864cbca15888549 upstream.
The member data in struct hclge_desc is type of __le32, it needs endian
conversion before using it, and some functions of debugfs didn't do that,
so this patch fixes it.
Fixes: c0ebebb9ccc1 ("net: hns3: Add "dcb register" status information query function")
