From 2fd7037122a920ae22377b06aa5b32651cc71f13 Mon Sep 17 00:00:00 2001 From: Hector Martin Date: Sun, 29 Oct 2023 15:37:43 +0900 Subject: [PATCH] usb: xhci: Do not panic on event timeouts Now that we always check the return value, just return NULL on timeouts. We can still log the error since this is a problem, but it's not reason to panic.
