[PATCH] crypto: hisilicon/qm - fix incorrect parameters usage

From: Weili Qian <qianweili@huawei.com>
Date: 2022-09-24 10:17:41
Also in: lkml
Subsystem: crypto api, hisilicon qm driver, the rest · Maintainers: Herbert Xu, "David S. Miller", Weili Qian, Zhou Wang, Linus Torvalds

In qm_get_xqc_depth(), parameters low_bits and high_bits save
the values of the corresponding bits. However, the values saved by the
two parameters are opposite. As a result, the values returned to the
callers are incorrect.

Fixes: 129a9f340172 ("crypto: hisilicon/qm - get qp num and depth from hardware registers")
