[PATCH 4/5] crypto: hisilicon - change parameter passing of debugfs function

flat view
STALE1905d SUPERSEDED

From: Weili Qian <qianweili@huawei.com>
Date: 2021-08-07 10:37:11
Also in: lkml
Subsystem: crypto api, hisilicon qm driver, hisilicon security engine v2 driver (sec2), hisilicon zip controller driver, the rest · Maintainers: Herbert Xu, "David S. Miller", Weili Qian, Zhou Wang, Longfang Liu, Chenghai Huang, Linus Torvalds

Status: Superseded by v2 (posted 2021-08-13). [go to v2]

Revision v1 (2 revisions archived).

Revisions (2)
  1. v1 current
  2. v2 [diff against previous] 
To avoid repeatedly obtaining 'qm' from 'filp', parameter passing of
debugfs function directly use 'qm' instead of 'filp'.
