[PATCH] usb: usb-acpi: fix uninitialized variable in usb_acpi_get_connect_type()

From: Dan Carpenter
Date: Fri Mar 15 2024 - 11:21:19 EST


The "pld" pointer is uninitialized if acpi_get_physical_device_location()
fails. Initialize it to NULL.

Fixes: f3ac348e6e04 ("usb: usb-acpi: Set port connect type of not connectable ports correctly")
