Include <linux/of.h> in source files that need it. Some of DRM's source code gets OF header via drm_crtc_helper.h and <linux/fb.h>, which can leed to unnecessary recompilation. In drm_modes.c, add a comment on the reason for still including <linux/fb.h>. The header file is required to get KHZ2PICOS(). The macro is part of the UAPI headers, so it cannot be moved to a less prominent location. v2: * include <linux/of.h> in komeda_drv.c (kernel test robot) Signed-off-by: Thomas Zimmermann <tzimmermann@xxxxxxx> --- drivers/gpu/drm/arm/display/komeda/komeda_drv.c | 1 + drivers/gpu/drm/drm_modes.c | 5 +++-- drivers/gpu/drm/panel/panel-ronbo-rb070d30.c | 1 + 3 files changed, 5 insertions(+), 2 deletions(-) diff --git a/drivers/gpu/drm/arm/display/komeda/komeda_drv.c b/drivers/gpu/drm/arm/display/komeda/komeda_drv.c index 3f4e719eebd8..28f76e07dd95 100644 --- a/drivers/gpu/drm/arm/display/komeda/komeda_drv.c +++ b/drivers/gpu/drm/arm/display/komeda/komeda_drv.c @@ -6,6 +6,7 @@ */ #include <linux/module.h> #include <linux/kernel.h> +#include <linux/of.h> #include <linux/platform_device.h> #include <linux/component.h> #include <linux/pm_runtime.h> diff --git a/drivers/gpu/drm/drm_modes.c b/drivers/gpu/drm/drm_modes.c index be030f4a5311..40d482a01178 100644 --- a/drivers/gpu/drm/drm_modes.c +++ b/drivers/gpu/drm/drm_modes.c @@ -31,10 +31,11 @@ */ #include <linux/ctype.h> +#include <linux/export.h> +#include <linux/fb.h> /* for KHZ2PICOS() */ #include <linux/list.h> #include <linux/list_sort.h> -#include <linux/export.h> -#include <linux/fb.h> +#include <linux/of.h> #include <video/of_display_timing.h> #include <video/of_videomode.h> diff --git a/drivers/gpu/drm/panel/panel-ronbo-rb070d30.c b/drivers/gpu/drm/panel/panel-ronbo-rb070d30.c index a8a98c91b13c..866d1bf5530e 100644 --- a/drivers/gpu/drm/panel/panel-ronbo-rb070d30.c +++ b/drivers/gpu/drm/panel/panel-ronbo-rb070d30.c @@ -15,6 +15,7 @@ #include <linux/kernel.h> #include <linux/media-bus-format.h> #include <linux/module.h> +#include <linux/of.h> #include <linux/gpio/consumer.h> #include <linux/regulator/consumer.h> -- 2.39.0
