Subject: [PATCH v2 10/18] thunderbolt: Add tb_switch_get()
Date: Mon, 26 Feb 2018 17:10:40 +0300 [thread overview]
Message-ID: <20180226141048.83949-11-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20180226141048.83949-1-mika.westerberg@linux.intel.com>
Sometimes there is need for increasing reference count of a switch as
well. This also follows what we have for xdomains.
