Subject: [PATCH v3 2/2] platform/x86: dell-ddv: Prefer asynchronous probing
Date: Thu, 9 Feb 2023 22:15:03 +0100 [thread overview]
Message-ID: <20230209211503.2739-3-W_Armin@gmx.de> (raw)
In-Reply-To: <20230209211503.2739-1-W_Armin@gmx.de>
During probe, both sensor buffers need to be queried to
initialize the hwmon channels. This might be slow on some
machines, causing a unnecessary delay during boot.
Mark the driver with PROBE_PREFER_ASYNCHRONOUS so that it
can be probed asynchronously.
