From 5198c0eeb8ff98ee673a2420ba96d93c477c6ef4 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 11 Aug 2023 11:47:15 -0400 Subject: [PATCH] USB: core: Fix unused variable warning in usb_alloc_dev() The kernel test robot reported that a recent commit caused a "variable set but not used" warning. As a result of that commit, the variable no longer serves any purpose; it should be removed.
