Subject: media: vsp1: Export missing vsp1_isp_free_buffer symbol
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=b32655a5f4c1a3b830f05fe3d43e17b2c4d09146;p=users%2Fhch%2Fmisc.git

media: vsp1: Export missing vsp1_isp_free_buffer symbol

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.
