[Digikam-devel] [PATCH] Remove dependance on libgphoto2 CamList internals

[Hans Ulrich Niedermann]

This patch makes gpiface.cpp use the libgphoto2 CamList type in
the way it was intended to be.

The internals of the CamList type may eventually become private,
and this removes digikam's dependency on those internals.
