We get 2 warnings when building kernel with W=1: drivers/gpu/drm/radeon/radeon_device.c:1961:5: warning: no previous prototype for 'radeon_debugfs_init' [-Wmissing-prototypes] drivers/gpu/drm/radeon/radeon_device.c:1966:6: warning: no previous prototype for 'radeon_debugfs_cleanup' [-Wmissing-prototypes]
