Daniel Vetter c3b790ea07 drm: Manage drm_mode_config_init with drmm_ ... drm_mode_config_cleanup is idempotent, so no harm in calling this twice. This allows us to gradually switch drivers over by removing explicit drm_mode_config_cleanup calls. With this step it's now also possible that (at least for simple drivers) automatic resource cleanup can be done correctly without a drm_driver->release hook. Therefore allow this now in devm_drm_dev_init(). Also with drmm_ explicit drm_driver->release hooks are kinda not the best option: Drivers can always just register their current release hook with drmm_add_action, but even better they could split them up to simplify the unwinding for the driver load failure case. So deprecate that hook to discourage future users. v2: Fixup the example in the kerneldoc too. v3: - For paranoia, double check that minor->dev == dev in the release hook, because I botched the pointer math in the drmm library. - Call drm_mode_config_cleanup when drmm_add_action fails, we'd be missing some mutex_destroy and ida_cleanup otherwise (Laurent) v4: Add a drmm_add_action_or_reset (like devm_ has) to encapsulate this pattern (Noralf). v5: Fix oversight in the new drmm_add_action_or_reset macro (Noralf) v4: Review from Sam: - drmm_mode_config_init wrapper (also suggested by Thomas) - improve commit message, explain better why ->relase is deprecated v5: - Make drmm_ the main function, with the old one as compat wrapper (Sam) - Add FIXME comments to drm_mode_config_cleanup/init() that drivers shouldn't use these anymore. - Move drmm_add_action_or_reset helper to an earlier patch.
