[libcamera-devel] [PATCH 3/4] cam: fix printing of camera name

[Niklas Söderlund]

Since commit c8c546fe99a343c1 ("cam: options: Add option type handling
to options parser") introduced type handling for options the context the
option is read became important. When reading the camera option for
printing there is no explicit context to print it as a string and
instead the int context was chosen resulting in:

    $ cam --camera foo
    Camera 0 not found

While the expected output is:

    $ cam --camera foo
    Camera foo not found

Fix this by providing the correct context for the camera option when
printing it.
