Subject: [PATCH 2/5] regulator: add dummy of_find_regulator_by_node
Date: Tue,  1 May 2018 21:00:11 +0800	[thread overview]
Message-ID: <1525179614-14571-3-git-send-email-changbin.du@intel.com> (raw)
In-Reply-To: <1525179614-14571-1-git-send-email-changbin.du@intel.com>

From: Changbin Du <changbin.du@intel.com>

If device tree is not enabled, of_find_regulator_by_node() should have
a dummy function since the function call is still there.
