mainline inclusion from mainline-v5.17-rc1 commit 045a31b95509c8f25f5f04ec5e0dec5cd09f2c5f category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I6IXQP CVE: CVE-2023-23000
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
--------------------------------
callers of tegra_xusb_find_port_node() function only do NULL checking for the return value. return NULL instead of ERR_PTR(-ENOMEM) to keep consistent.
