The branch main has been updated by emaste: URL: https://cgit.FreeBSD.org/src/commit/?id=754decef384a1ab30b39704264742fa33bfa365e commit 754decef384a1ab30b39704264742fa33bfa365e Author: Ed Maste <emaste@FreeBSD.org> AuthorDate: 2022-06-21 18:50:04 +0000 Commit: Ed Maste <emaste@FreeBSD.org> CommitDate: 2022-06-21 18:50:04 +0000 Retire snd_gusc ISA sound card driver snd_gusc supported the Gravis UltraSound MAX and UltraSound PnP sound cards. ISA sound card drivers are deprecated as discussed on the current[1] and stable[2] mailing lists. Deprecation notices were added in e39ec8933be4 and MFCd to stable branches. Driver removals are being committed individually so that specific drivers can be restored if necessary (either in FreeBSD or by downstream projects).
