From: Laurent Pinchart Date: Tue, 17 Nov 2015 14:23:23 +0000 (-0200) Subject: [media] v4l: vsp1: Consolidate entity ops in a struct vsp1_entity_operations X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5243453472e7bce74764ddf9f206450dcc8769c5;p=linux-beck.git [media] v4l: vsp1: Consolidate entity ops in a struct vsp1_entity_operations Entities have two operations, a destroy operation stored directly in vsp1_entity and a set_memory operation stored in a vsp1_rwpf_operations structure. Move the two to a more generic vsp1_entity_operations structure that will serve to implement additional operations.
