This patchset moves legacy, non-KMS driver state from struct drm_driver into struct drm_legacy_state. Only non-KMS drivers provide an instance of the latter structure. One special case is nouveau, which supports legacy interfaces. It also provides an instance of the legacy state if the legacy interfaces have been enabled (i.e., defines the config option CONFIG_NOUVEAU_LEGACY_CTX_SUPPORT)
I reviewed all call sites of legacy state and functions to verify that DRIVER_LEGACY or DRIVER_KMS_LEGACY_CONTEXT is set on the device; or that DRIVER_MODESET is not set. With the mutable KMS state removed, instances of struct drm_driver can be declared as constant. The patchset modifies the DRM core accordingly. Individual drivers can follow later on.
