From 43d2479687c93ed9b93774ef9b46b37de5b3efcc Mon Sep 17 00:00:00 2001 From: Dong Aisheng Date: Thu, 19 Nov 2020 19:43:02 +0800 Subject: clk: imx: scu: remove the calling of device_is_bound The device_is_bound() is invisible to drivers when built as modules. It's also not aimed to be used by drivers according to Greg K.H. Let's remove it from clk-scu driver and find another way to do proper driver loading sequence.
