Subject: [PATCH resend] thunderbolt: Fix reset response_type
Date: Wed, 16 Aug 2017 11:54:17 +0300	[thread overview]
Message-ID: <20170816085417.7xlnl54jkx2p36qs@mwanda> (raw)
In-Reply-To: <735914a9-3d8f-7d98-35c3-6e2e046e70c2@canonical.com>

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.

Fixes: d7f781bfdbf4 ("thunderbolt: Rework control channel to be more reliable")
