This series includes work on various debugfs functions both in drm/core and across various drivers in the subsystem. Since commit 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail), drm_debugfs_create_files() does not fail and only returns zero. This series therefore removes the left over error handling and checks for its return value across drm drivers.
As a result of these changes, most drm_debugfs functions are converted to return void in this series. This also enables the drm_driver,debugfs_init() hook to be changed to return void.
Wambui Karuga (21): drm/debugfs: remove checks for return value of drm_debugfs functions. drm: convert the drm_driver.debugfs_init() hook to return void. drm: convert drm_debugfs functions to return void drm/vram-helper: make drm_vram_mm_debugfs_init() return void drm/vc4: remove check of return value of drm_debugfs functions drm/arc: make arcpgu_debugfs_init return void drm/arm: make hdlcd_debugfs_init() return void drm/etnaviv: remove check for return value of drm_debugfs function drm/nouveau: remove checks for return value of debugfs functions drm/tegra: remove checks for debugfs functions return value drm/v3d: make v3d_debugfs_init return void drm/msm: remove checks for return value of drm_debugfs functions. drm/omapdrm: remove checks for return value of drm_debugfs functions. drm/pl111: make pl111_debugfs_init return void drm/sti: remove use drm_debugfs functions as return value drm/i915: make *_debugfs_register() functions return void. drm/tilcdc: remove check for return value of debugfs functions. drm/virtio: make virtio_gpu_debugfs() return void. drm/mipi_dbi: make midi_dbi_debugfs_init() return void. drm/qxl: have debugfs functions return void. drm/arm: have malidp_debufs_init() return void
