From 42601e356bfa8123e44a3d726d4abd4164a71f7c Mon Sep 17 00:00:00 2001 From: Junlin Yang Date: Mon, 21 Jun 2021 21:24:15 +0800 Subject: usb: class: cdc-wdm: return the correct errno code The "rv" is initialized to "-ENOMEM", because "rv" is re-assigned to "-EINVAL", when kmalloc & usb_alloc_urb failed, the return value should return "-ENOMEM" rather than "-EINVAL",so the "rv" assignment is placed in the position where usb_endpoint_is_int_in is false.
