From afc2c9a2c359c850cea097c60a5f2b596efbbd88 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Fri, 22 Mar 2013 13:32:10 -0400 Subject: [PATCH] USB: EHCI: remove unused variable in unlink_empty_async() This patch (as1669) removes the check_unlinks_later flag in ehci-hcd's unlink_empty_async(). It wasn't being used for anything and should have been removed in an earlier patch, but I forgot about it.
