From 457e7911dfb81a31834c25ab7f13a4475350459b Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Fri, 18 Jun 2021 14:29:12 +0200 Subject: [PATCH] media: uvcvideo: Use dev->name for querycap() Use the device name for the card name instead of vdev->name. That way all the devices have a different name instead of the common vdev->name.
