Subject: [PATCH v2 1/4] driver core: Check for supplier requiring PM at link creation
Date: Thu, 1 Oct 2026 14:20:20 +0100 [thread overview]
Message-ID: <20261001132023.17032-2-alucerop@amd.com> (raw)
In-Reply-To: <20261001132023.17032-1-alucerop@amd.com>
From: Alejandro Lucero <alucerop@amd.com>
PM initialization could not be necessary for some devices.
Avoid checking for supplier PM initialization if so.
