Author: asomers Date: Fri Jan 20 21:21:41 2017 New Revision: 312558 URL: https://svnweb.freebsd.org/changeset/base/312558 Log: Misc Coverity fixes in camcontrol(8) CID 1229913 Fix output of "camcontrol persist -i report_capabilities". The reported Persistent Reservation Types were wrong in all cases. CID 1356029 Annotate the code so Coverity will know that this is a false positive. CID 1366830 Fix a memory leak in "camcontrol timestamp -s" CID 1366832 Fix a segfault that could be caused by bad drive firmware Also, fix the man page entry for the "camcontrol epc state" command to match what the code does.
