Subject: [Intel-gfx] [PATCH 24/29] drm/i915/tc: Don't connect the PHY in intel_tc_port_connected()
Date: Thu, 23 Mar 2023 16:20:30 +0200 [thread overview]
Message-ID: <20230323142035.1432621-25-imre.deak@intel.com> (raw)
In-Reply-To: <20230323142035.1432621-1-imre.deak@intel.com>
Connecting the PHY for connector probing - also blocking TC-cold - isn't
required and has some overhead. Taking only the mutex is sufficient, so
do that.
