From dbeb38d93a6da89c99801a9c70607920be72b94e Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Mon, 29 Apr 2019 15:50:11 +0300 Subject: [PATCH] drm/i915: extract intel_hotplug.h from intel_drv.h and i915_drv.h It used to be handy that we only had a couple of headers, but over time intel_drv.h has become unwieldy. Extract declarations to a separate header file corresponding to the implementation module, clarifying the modularity of the driver. Ensure the new header is self-contained, and do so with minimal further includes, using forward declarations as needed. Include the new header only where needed, and sort the modified include directives while at it and as needed. No functional changes. v2: fix sparse warnings on undeclared global functions Reviewed-by: Chris Wilson Signed-off-by: Jani Nikula Link: https://patchwork.freedesktop.org/patch/msgid/20190429125011.10876-1-jani.nikula@intel.com --- drivers/gpu/drm/i915/Makefile.header-test | 1 + drivers/gpu/drm/i915/i915_drv.c | 1 + drivers/gpu/drm/i915/i915_drv.h | 11 --------- drivers/gpu/drm/i915/i915_irq.c | 1 + drivers/gpu/drm/i915/intel_crt.c | 1 + drivers/gpu/drm/i915/intel_ddi.c | 1 + drivers/gpu/drm/i915/intel_display.c | 1 + drivers/gpu/drm/i915/intel_dp.c | 1 + drivers/gpu/drm/i915/intel_drv.h | 5 ---- drivers/gpu/drm/i915/intel_hdmi.c | 1 + drivers/gpu/drm/i915/intel_hotplug.c | 1 + drivers/gpu/drm/i915/intel_hotplug.h | 30 +++++++++++++++++++++++ drivers/gpu/drm/i915/intel_runtime_pm.c | 1 + drivers/gpu/drm/i915/intel_sdvo.c | 1 + drivers/gpu/drm/i915/intel_tv.c | 1 + 15 files changed, 42 insertions(+), 16 deletions(-) create mode 100644 drivers/gpu/drm/i915/intel_hotplug.h diff --git a/drivers/gpu/drm/i915/Makefile.header-test b/drivers/gpu/drm/i915/Makefile.header-test index beda60ea8dbf..dafaaa2ec9db 100644 --- a/drivers/gpu/drm/i915/Makefile.header-test +++ b/drivers/gpu/drm/i915/Makefile.header-test @@ -36,6 +36,7 @@ header_test := \ intel_frontbuffer.h \ intel_hdcp.h \ intel_hdmi.h \ + intel_hotplug.h \ intel_lspcon.h \ intel_lvds.h \ intel_panel.h \ diff --git a/drivers/gpu/drm/i915/i915_drv.c b/drivers/gpu/drm/i915/i915_drv.c index 4cfdc2741ef5..b891a6aa7980 100644 --- a/drivers/gpu/drm/i915/i915_drv.c +++ b/drivers/gpu/drm/i915/i915_drv.c @@ -63,6 +63,7 @@ #include "intel_dp.h" #include "intel_drv.h" #include "intel_fbdev.h" +#include "intel_hotplug.h" #include "intel_pm.h" #include "intel_sprite.h" #include "intel_uc.h" diff --git a/drivers/gpu/drm/i915/i915_drv.h b/drivers/gpu/drm/i915/i915_drv.h index df9ac3943993..7a6c21df6b37 100644 --- a/drivers/gpu/drm/i915/i915_drv.h +++ b/drivers/gpu/drm/i915/i915_drv.h @@ -2717,17 +2717,6 @@ int intel_engines_init(struct drm_i915_private *dev_priv);
