Subject: [PATCH v3 6/6] i915/display/dp: send a more fine-grained link-status uevent
Date: Fri, 15 Oct 2021 16:33:46 +0000 [thread overview]
Message-ID: <20211015163336.95188-7-contact@emersion.fr> (raw)
In-Reply-To: <20211015163336.95188-1-contact@emersion.fr>
When link-status changes, send a hotplug uevent which contains the
connector and property ID. That way, user-space can more easily
figure out that only the link-status property of this connector has
been updated.
