[libcamera-devel] [PATCH v3 03/16] test: control_list: Test ControlList::merge()

[Jacopo Mondi]

Test the newly introduce ControlList::merge() method by creating
a new list with a single control and merging it with the existing one.

Test that the merged list contains all the controls and their values
are not changed.
