2288 	 * So we can safely release the lock here; and we MUST release the

2291 	 * If we keep the lock here then the lock ordering in this path is:
2292 	 * 1. tcpm_pd_rx_handler take the tcpm port lock
2293 	 * 2. One of the typec_altmode_* calls below takes the alt-mode's lock
2296 	 * 1. alt-mode driver takes the alt-mode's lock

2300 	 * Dropping our lock here avoids this.
