[libcamera-devel] [PATCH v3] lc-compliance: Add test to call multiple configure()

[Nícolas F. R. A. Prado]

Add a test to lc-compliance that calls configure() multiple times on the
camera before starting to capture. This isn't a common pattern for
applications but is allowed and so should be tested by lc-compliance.
