The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=31610e34b7e39d573d927ea98346c88f23cabdab commit 31610e34b7e39d573d927ea98346c88f23cabdab Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2023-05-05 21:59:15 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2023-05-06 17:49:19 +0000 hwpmc: don't use deprecated copystr(9) It is just wrapper around strlcpy(), but results in more complicated code. Clean this up to use strlcpy() or snprintf() as appropriate.
