Initialize i915's fbdev client by giving an instance of struct drm_client_funcs to drm_client_init(). Also clean up with drm_client_release(). Doing this in i915 prevents fbdev helpers from initializing and releasing the client internally (see drm_fb_helper_init()). No functional change yet; the client callbacks will be filled later. v6: * rename client to "intel-fbdev" (Jouni) v2: * call drm_fb_helper_unprepare() in error handling (Jani) * fix typo in commit message (Sam) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> --- drivers/gpu/drm/i915/display/intel_fbdev.c | 43 ++++++++++++++++++++-- 1 file changed, 39 insertions(+), 4 deletions(-)
