Subject: [PATCH 4.13 23/47] thunderbolt: Fix reset response_type

4.13-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 02729d17b1b818cc38a6b6319231a0cd86b132e4 upstream.

There is a mistake here where we accidentally use sizeof(TB_CFG_PKG_RESET)
instead of just TB_CFG_PKG_RESET.  The size of an int is 4 so it's the
same as TB_CFG_PKG_NOTIFY_ACK.
