Oh yeah, I just noticed that this patch causes a build failure, so I backed it out again. If there's dependencies on other work, it's probably best to take this through drm-misc, in which case: Acked-by: Thierry Reding <treding@nvidia.com> Let me know if you'd prefer me to apply this to drm/tegra instead.

Yeah I'm going to pull in the entire series through -misc rsn. -Daniel

Since 987d65d01356 (drm: debugfs: make drm_debugfs_create_files() never fail) there is no need to check the return value of drm_debugfs_create_files(). Therefore, remove the return checks and error handling of the drm_debugfs_create_files() function from various debugfs init functions in drm/tegra and have them return 0 directly. This change also includes removing the use of drm_debugfs_create_files as a return value in tegra_debugfs_init() and have the function declared as void.
