6.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chenghai Huang <huangchenghai2@xxxxxxxxxx>
commit cd26cd65476711e2c69e0a049c0eeef4b743f5ac upstream.
Offset based on (id * size) is wrong for sqc and cqc.
(*sqc/*cqc + 1) can already offset sizeof(struct(Xqc)) length.
Fixes: 15f112f9cef5 ("crypto: hisilicon/debugfs - mask the unnecessary info from the dump")
