Hi Brian, Glad to hear that you had it on your radar and already figured it out. > > I worked around this by patching v4l2-compliance to allow overriding the > device's driver name: > https://lore.kernel.org/all/[email protected]/. > There are more details in [PATCH v5 0/5] of this series if you're curious: > https://lore.kernel.org/all/[email protected]/ Ah true, my bad! I skipped the note when checking your results.
