nvme_ns_get_transport_handle is creating a handle on demand, which can fail. Thus we need to propagate this error case and not blindly access the handle later and cause a NULL pointer access. Signed-off-by: Daniel Wagner <wagi@kernel.org>
The scanning can fail due to missing permissions etc. Thus propagate this error code instead creating invalid objects. Signed-off-by: Daniel Wagner <wagi@kernel.org>
Replace nvme_scan with nvme_scan_topology and ignore any ENOENT and EACCES. Either the nvme module is not loaded/present or the current user might now have permissions to access the device. Signed-off-by: Daniel Wagner <wagi@kernel.org>

The problem with this function is that it does several things at once which prevents fine grained error handling. And almost every user of this function was not interested in reading a config file. Thus open code this and handle the ENOENT and EACCES case. For the Python binding we just ignore any nvme_scan_topology and nvme_read_config error because this happens inside the global context constructor Signed-off-by: Daniel Wagner <wagi@kernel.org>
The scan helpers should also return the error code instead the generic -1. Fixes: f4c6eee ("rrc: return error codes directly") Signed-off-by: Daniel Wagner <wagi@kernel.org>

So this version is no passing a test package build: https://build.opensuse.org/package/show/home:wagi:branches:Base:System/nvme-cli |

When running the test suite on machine under normal user context, the test might fail because of not enough permissions. While improving the error propagation in the scan code, take the opertunity to handle these errors more gracefully in the tests suites.
