Subject: [PATCH v2 4/9] PCI: mark USB4 devices as removable
Date: Thu, 10 Feb 2022 16:43:24 -0600 [thread overview]
Message-ID: <20220210224329.2793-5-mario.limonciello@amd.com> (raw)
In-Reply-To: <20220210224329.2793-1-mario.limonciello@amd.com>
USB4 class devices are also removable like Intel Thunderbolt devices.
Drivers of downstream devices use this information to declare functional
differences in how the drivers perform by knowing that they are connected
to an upstream TBT/USB4 port.
