+Subject: extcon: usbc-tusb320: Call the Type-C IRQ handler only if a port is registered
+
+From: Yassine Oudjana <y.oudjana@protonmail.com>
+
+commit 341fd15e2e18c24d5c738496cfc3d7a272241201 upstream.
+
+Commit bf7571c00dca ("extcon: usbc-tusb320: Add USB TYPE-C support")
+added an optional Type-C interface to the driver but missed to check
+if it is in use when calling the IRQ handler. This causes an oops on
+devices currently using the old extcon interface. Check if a Type-C
+port is registered before calling the Type-C IRQ handler.
+
+Fixes: bf7571c00dca ("extcon: usbc-tusb320: Add USB TYPE-C support")
