Module Name: src Committed By: riastradh Date: Sun Apr 17 13:17:19 UTC 2022
Modified Files: src/sys/dev/usb: uvideo.c Log Message: uvideo(4): Convert conditional to KASSERT in uvideo_attach. usb_desc_iter_next_interface no longer returns truncated interface descriptors, so we no longer have to check for that here.
