media: vsp1: Export missing vsp1_isp_free_buffer symbol

Laurent Pinchart · Hans Verkuil · commit b32655a5f4c1 · 2025-09-17T12:14:05.000+02:00
The vsp1_isp_free_buffer() function implemented by the vsp1 driver is part of the API exposed to the rcar-isp driver. All other symbols except that one are properly exported. Fix it.
