It does not support runtime switching without a full restart. On older firmware, this accidentally worked to some degree due to missing checks, but couldn't be supported properly, because it left the 6 GHz channels uncalibrated. Newer firmware refuses to start on either band if the passed EEPROM data indicates support for both. Deal with this limitation by using a module parameter to specify the preferred band in case both are supported.

Fix the crash by introducing open() and close() methods for the port and check if the port is open before trying to access psmouse instance.

These are struct drm_mode_config.connection_mutex and struct drm_mode_config.mutex. - It does not use drm_helper_probe_detect(), which helps with the details of locking and detection. - It uses the connector's status field to determine a change to the connector status. The epoch_counter field is the correct one. The field signals a change even if the connector status' value did not change. Replace the code with a call to drm_connector_helper_hpd_irq_event(), which fixes all these problems.
