2.30.0
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.

The cmd type can be extended. Currently, only four types of cmd
can be processed. Therefor, add the default processing branch
to intercept incorrect parameter input.

2.30.0
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.

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.

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.

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.

The AIV is one of the SEC resources. When releasing resources,
it need to release the AIV resources at the same time.
Otherwise, memory leakage occurs.
