The branch main has been updated by zlei: URL: https://cgit.FreeBSD.org/src/commit/?id=5f97656fa334b494d70866cb1bfff406d3efd92d commit 5f97656fa334b494d70866cb1bfff406d3efd92d Author: Zhenlei Huang <zlei@FreeBSD.org> AuthorDate: 2024-09-03 10:25:29 +0000 Commit: Zhenlei Huang <zlei@FreeBSD.org> CommitDate: 2024-09-03 10:25:29 +0000 ice(4): Stop checking for failures from malloc(M_WAITOK) As a consequence now ice_alloc_vsi_qmap() does not fail. Remove unneeded error checks.
