[PATCH 0/3] crypto: hisilicon - improve backlog handling

[ZongYu Wu]

From: Chenghai Huang <huangchenghai2@xxxxxxxxxx>

This series improves backlog handling for HiSilicon crypto drivers.
The ZIP and HPRE drivers are extended to support backlog queuing when
the hardware queue is temporarily busy. Instead of failing requests
immediately under hardware congestion, requests can now be queued and
resubmitted when previous requests complete.

The series also fixes a use-after-free issue in the SEC2 backlog path.
The crypto core may release the request and its tfm context immediately
after crypto_request_complete() returns. The SEC2 driver must therefore
avoid accessing context memory that may already have been freed while
processing backlog requests.
