The method of hem free for SCC context is different from qp context.
In the current version, if free SCC hem during the execution of qp free,
there may be smmu error as below:
arm-smmu-v3 arm-smmu-v3.1.auto: event 0x10 received:
arm-smmu-v3 arm-smmu-v3.1.auto: 0x00007d0000000010
arm-smmu-v3 arm-smmu-v3.1.auto: 0x000012000000017c
arm-smmu-v3 arm-smmu-v3.1.auto: 0x00000000000009e0
arm-smmu-v3 arm-smmu-v3.1.auto: 0x0000000000000000
As SCC context is still used by hardware after qp free, we can solve this
problem by removing SCC hem free from hns_roce_qp_free.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
