[PATCH v2 1/9] crypto: hisilicon/sec - Add the condition for configuring the sriov function

[Chenghai Huang]

When CONFIG_PCI_IOV is disabled, the SRIOV configuration
function is not required. An error occurs if this function is
incorrectly called.

Consistent with other modules, add the condition for
configuring the sriov function of sec_pci_driver.

[PATCH v2 2/9] crypto: hisilicon/debugfs - Fix debugfs uninit process issue

[Chenghai Huang]

During the zip probe process, the debugfs failure does not stop
the probe. When debugfs initialization fails, jumping to the
error branch will also release regs, in addition to its own
rollback operation.

As a result, it may be released repeatedly during the regs
uninit process. Therefore, the null check needs to be added to
the regs uninit process.

[PATCH v2 3/9] crypto: hisilicon/sgl - Delete redundant parameter verification

[Chenghai Huang]

The input parameter check in acc_get_sgl is redundant. The
caller has been verified once. When the check is performed for
multiple times, the performance deteriorates.

So the redundant parameter verification is deleted, and the
index verification is changed to the module entry function for
verification.

[PATCH v2 4/9] crypto: hisilicon/debugfs - Fix the processing logic issue in the debugfs creation

[Chenghai Huang]

There is a scenario where the file directory is created but the
file attribute is not set. In this case, if a user accesses the
file, an error occurs.

So adjust the processing logic in the debugfs creation to
prevent the file from being accessed before the file attributes
such as the index are set.

[PATCH v2 6/9] crypto: hisilicon - Adjust debugfs creation and release order

[Chenghai Huang]

There is a scenario where the file directory is created but the
file memory is not set. In this case, if a user accesses the
file, an error occurs.

So during the creation process of debugfs, memory should be
allocated first before creating the directory. In the release
process, the directory should be deleted first before releasing
the memory to avoid the situation where the memory does not
exist when accessing the directory.

In addition, the directory released by the debugfs is a global
variable. When the debugfs of an accelerator fails to be
initialized, releasing the directory of the global variable
affects the debugfs initialization of other accelerators.
The debugfs root directory released by debugfs init should be a
member of qm, not a global variable.

it need to release the AIV resources at the same time.
Otherwise, memory leakage occurs.

[PATCH v2 8/9] crypto: hisilicon/debugfs - Resolve the problem of applying for redundant space in sq dump

[Chenghai Huang]

When dumping SQ, only the corresponding ID's SQE needs to be
dumped, and there is no need to apply for the entire SQE
memory. This is because excessive dump operations can lead to
memory resource waste.

Therefor apply for the space corresponding to sqe_id separately
to avoid space waste.
