Subject: [PATCH v1 01/11] drm/panel: make drm_panel.h self-contained
Date: Thu, 18 Jul 2019 18:14:57 +0200 [thread overview]
Message-ID: <20190718161507.2047-2-sam@ravnborg.org> (raw)
In-Reply-To: <20190718161507.2047-1-sam@ravnborg.org>
From: Jani Nikula <jani.nikula@intel.com>
Fix build warning if drm_panel.h is built with CONFIG_OF=n or
CONFIG_DRM_PANEL=n and included without the prerequisite err.h:
./include/drm/drm_panel.h: In function ‘of_drm_find_panel’:
./include/drm/drm_panel.h:203:9: error: implicit declaration of function ‘ERR_PTR’ [-Werror=implicit-function-declaration]
return ERR_PTR(-ENODEV);
^~~~~~~
./include/drm/drm_panel.h:203:9: error: returning ‘int’ from a function with return type ‘struct drm_panel *’ makes pointer from integer without a cast [-Werror=int-conversion]
return ERR_PTR(-ENODEV);
^~~~~~~~~~~~~~~~
Fixes: 5fa8e4a22182 ("drm/panel: Make of_drm_find_panel() return an ERR_PTR() instead of NULL")
