Laurent maybe? There's a drmP.h cleanup in the R-Car DU driver, but it doesn't conflict wi= th=20 this patch, the combination of both compiles fine. > Jani, ack on this? > -Daniel > --- [snip] > drivers/gpu/drm/bridge/adv7511/adv7511.h | 5 +- > drivers/gpu/drm/bridge/analogix-anx78xx.c | 2 +- > drivers/gpu/drm/bridge/dumb-vga-dac.c | 2 +- > drivers/gpu/drm/bridge/synopsys/dw-hdmi.c | 2 +- > drivers/gpu/drm/bridge/ti-tfp410.c | 2 +- > drivers/gpu/drm/drm_atomic_helper.c | 1 - > drivers/gpu/drm/drm_dp_mst_topology.c | 2 +- > drivers/gpu/drm/drm_modeset_helper.c | 2 +- > drivers/gpu/drm/drm_probe_helper.c | 2 +- > drivers/gpu/drm/drm_simple_kms_helper.c | 2 +- > drivers/gpu/drm/omapdrm/omap_connector.c | 2 +- > drivers/gpu/drm/omapdrm/omap_crtc.c | 2 +- > drivers/gpu/drm/omapdrm/omap_drv.c | 2 +- > drivers/gpu/drm/omapdrm/omap_drv.h | 2 +- > drivers/gpu/drm/omapdrm/omap_encoder.c | 2 +- > drivers/gpu/drm/omapdrm/omap_fb.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_du_crtc.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_du_drv.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_du_encoder.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_du_kms.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_du_plane.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_du_vsp.c | 2 +- > drivers/gpu/drm/rcar-du/rcar_lvds.c | 2 +- > drivers/gpu/drm/shmobile/shmob_drm_crtc.c | 1 + > drivers/gpu/drm/shmobile/shmob_drm_drv.c | 1 + > drivers/gpu/drm/shmobile/shmob_drm_kms.c | 1 + > include/drm/drm_crtc_helper.h | 16 ------ > include/drm/drm_probe_helper.h | 50 +++++++++++++++++++ =46or the above files, with the comments below addressed, Reviewed-by: Laurent Pinchart > 227 files changed, 289 insertions(+), 200 deletions(-) > create mode 100644 include/drm/drm_probe_helper.h [snip] > diff --git a/drivers/gpu/drm/bridge/adv7511/adv7511.h > b/drivers/gpu/drm/bridge/adv7511/adv7511.h index 73d8ccb97742..d52ffab41e= b4 > 100644 > --- a/drivers/gpu/drm/bridge/adv7511/adv7511.h > +++ b/drivers/gpu/drm/bridge/adv7511/adv7511.h > @@ -14,8 +14,11 @@ > #include > #include >=20 > -#include > +#include The probe helpers are needed in adv7511_drv.c only, I would move the includ= e=20 there. > #include > +#include > +#include > +#include Please keep the headers alphabetically sorted, here and in all other driver= s. > #define ADV7511_REG_CHIP_REVISION 0x00 > #define ADV7511_REG_N0 0x01 [snip] > diff --git a/drivers/gpu/drm/omapdrm/omap_crtc.c > b/drivers/gpu/drm/omapdrm/omap_crtc.c index 40acf4ce7c9f..9beb0edd5ffa > 100644 > --- a/drivers/gpu/drm/omapdrm/omap_crtc.c > +++ b/drivers/gpu/drm/omapdrm/omap_crtc.c > @@ -18,7 +18,7 @@ > #include > #include > #include > -#include > +#include This file doesn't use the probe helpers, you can drop this. > #include > #include > #include [snip] > diff --git a/drivers/gpu/drm/omapdrm/omap_drv.h > b/drivers/gpu/drm/omapdrm/omap_drv.h index bd7f2c227a25..513ae8ab5e64 > 100644 > --- a/drivers/gpu/drm/omapdrm/omap_drv.h > +++ b/drivers/gpu/drm/omapdrm/omap_drv.h > @@ -23,7 +23,7 @@ > #include >=20 > #include > -#include > +#include This isn't needed globally in the driver either. > #include > #include >=20 > diff --git a/drivers/gpu/drm/omapdrm/omap_encoder.c > b/drivers/gpu/drm/omapdrm/omap_encoder.c index 148b6b20274f..cd2328fa4ba6 > 100644 > --- a/drivers/gpu/drm/omapdrm/omap_encoder.c > +++ b/drivers/gpu/drm/omapdrm/omap_encoder.c > @@ -18,7 +18,7 @@ > #include >=20 > #include > -#include > +#include As far as I can tell this is only used to include=20 drm_modeset_helper_vtables.h.
