Author: mav Date: Mon Mar 6 06:20:58 2017 New Revision: 314730 URL: https://svnweb.freebsd.org/changeset/base/314730 Log: MFC r314045: Remove duplicate INOT allocation. For some reason isp_handle_platform_notify_fc() allocated INOT just before calling isp_handle_platform_target_tmf(), which also allocates INOT. It seems to be a braino introduced in r196008.
