| |
Make these structures const as they are only stored in the funcs field of a drm_mode_config structure which is of type const. Done using Coccinelle:
@match disable optional_qualifier@ identifier s; @@ static struct drm_mode_config_funcs s = {...};
@ref@ position p; identifier match.s; @@ s@p
@good1@ identifier y; position ref.p; identifier match.s; @@ struct drm_mode_config y = {...,.funcs=&s@p,...};
@good2@ struct drm_mode_config y; identifier match.s; position ref.p; @@ y.funcs = &s@p
@bad depends on !good1 && !good2@ position ref.p; identifier match.s; @@ s@p
@depends on forall !bad disable optional_qualifier@ identifier match.s; @@ static + const struct drm_mode_config_funcs s;
