USB: EHCI: remove unused variable in unlink_empty_async() (afc2c9a2) · Commits · 戴 / test

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. Signed-off-by:
