Subject: [PATCH 04/13] thunderbolt: Check for unplugged router in tb_switch_clx_disable()
Date: Tue, 3 Oct 2023 12:39:56 +0300 [thread overview]
Message-ID: <20231003094005.2676823-5-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20231003094005.2676823-1-mika.westerberg@linux.intel.com>
There is no point disabling CL states if the router is unplugged so in
that case return early.
