+Subject: thunderbolt: Check return value of tb_sw_read() in usb4_switch_op()
+
+From: Mika Westerberg <mika.westerberg@linux.intel.com>
+
+commit c3bf9930921b33edb31909006607e478751a6f5e upstream.
+
+The function misses checking return value of tb_sw_read() before it
+accesses the value that was read. Fix this by checking the return value
+first.
+
+Fixes: b04079837b20 ("thunderbolt: Add initial support for USB4")
