From: Miaoqian Lin <linmq006@gmail.com> stable inclusion from stable-v5.10.124 commit a44a8a762f7fe9ad3c065813d058e835a6180cb2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6E7 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit 3755278f078460b021cd0384562977bf2039a57a upstream. usb_create_hcd will alloc memory for hcd, and we should call usb_put_hcd to free it when platform_get_resource() fails to prevent memory leak. goto error2 label instead error1 to fix this.
