Date: Sun, 4 Aug 2019 18:20:18 +0800 [thread overview]
Message-ID: <1564914022-3710-9-git-send-email-hao.wu@intel.com> (raw)
In-Reply-To: <1564914022-3710-1-git-send-email-hao.wu@intel.com>
This patch makes uinit callback of sub features optional. With
this change, people don't need to prepare any empty uinit callback.
