From 026381fc5a06cdc3e41a6bae83486be6cbaae0a9 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Sat, 15 Dec 2018 12:19:52 +0000 Subject: [PATCH] misc: imx8: scu: use platdata instead of priv data priv data has not been allocated when doing bind, so it is wrong to use dev_get_priv in bind call back. Let's switch to use platdata in the driver to fix the issue.
