I think it would make sense to rework tpacpi_detect_brightness_capabilities() to just pr_debug() something like "firmware reports %d brightness levels" after it has processed the result of tpacpi_check_std_acpi_brightness_support(). We should leave any complaining about supported/unsupported to brightness_init(), so it would make sense to add a dbg_printk to brightness_init that reports "unsupported brightness mode, use acpi video or gpu drivers" when tp_features.bright_unkfw is not zero.
