Subject: drm/imx: ipuv3-plane: Make functions static when possible
Git-commit: 2ead44a5984b30fad7e6da507cdddb97f0401075
Patch-mainline: v4.16-rc7
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
ipu_plane_state_reset(), ipu_plane_duplicate_state() and
ipu_plane_destroy_state() are only used in this file, so make them static.
This fixes the following sparse warnings:
drivers/gpu/drm/imx/ipuv3-plane.c:275:6: warning: symbol 'ipu_plane_state_reset' was not declared. Should it be static?
drivers/gpu/drm/imx/ipuv3-plane.c:295:24: warning: symbol 'ipu_plane_duplicate_state' was not declared. Should it be static?
drivers/gpu/drm/imx/ipuv3-plane.c:309:6: warning: symbol 'ipu_plane_destroy_state' was not declared. Should it be static?
