+Subject: [PATCH] usb: typec: ucsi: clear USB role when partner lacks USB
+ data
+
+Commit 0c8ee850572 ("usb: typec: ucsi: Add UCSI_USB4_IMPLIES_USB quirk
+for X1E80100") gated the "partner advertises no USB data ->
+USB_ROLE_NONE" decision behind the UCSI_USB4_IMPLIES_USB quirk. On
+ports without that quirk (e.g. SM8750 / AYN Odin 3, pmic_glink UCSI)
+the USB data role is then never cleared for a charger-only partner, so
+it stays attached across system suspend. That keeps the USB power
+island up, and the deep-suspend firmware power-collapse hard-hangs the
+SoC when the cable is unplugged while suspended: dead screen, the SoC
+runs hot, only a forced reset recovers (7.0.x is fine, 7.1.x hangs).
+
+Restore the pre-0c8ee850572 behaviour: clear the USB role whenever the
+partner advertises no USB data.
