From: Ricardo Ribalda Date: Fri, 25 Jul 2025 11:01:29 +0000 (+0000) Subject: media: uvcvideo: Use intf instead of udev for printks X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5cdbca8967dc804829883e251a9d197b5fab4aed;p=thirdparty%2Fkernel%2Fstable.git media: uvcvideo: Use intf instead of udev for printks The UVC driver is a usb_interface driver. Use the correct device for printks to avoid confusions with other interface drivers associated to the same usb device.
