Subject: e_comp_wl_tbm: add egl_image_buffer_get func to E_Comp_wl_Tbm_Funcs
X-Git-Tag: submit/tizen/20201211.120426~1
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F13%2F249413%2F1;p=platform%2Fupstream%2Fenlightenment.git

e_comp_wl_tbm: add egl_image_buffer_get func to E_Comp_wl_Tbm_Funcs

egl_image_buffer_get func has to provide the tbm_surface_h for making the egl_image.
