The branch main has been updated by adrian: URL: https://cgit.FreeBSD.org/src/commit/?id=5d0258d4ea51738ae28262e01514bb4b78ec158d commit 5d0258d4ea51738ae28262e01514bb4b78ec158d Author: Abdelkader Boudih <freebsd@seuros.com> AuthorDate: 2026-08-09 16:58:33 +0000 Commit: Adrian Chadd <adrian@FreeBSD.org> CommitDate: 2026-08-09 16:58:36 +0000 fwcamctl: remove, superseded by the video(4) interface fwcam(4) no longer creates its own character device or implements the FWCAM_* ioctls; it registers with video(4) and is driven through the standard V4L2 interface on /dev/videoN.
