From 76f82a7ab3a724791d184e74529e96ad6947a98f Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 30 Jan 2012 21:14:29 +0100 Subject: [PATCH] USB: serial, use tty_standard_install But before that we need to reorder the calls so that we don't need to lower the reference counts if usb_autopm_get_interface fails.
