From 532f2435cfe94e54e01ba68572daa853d7752afa Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Fri, 11 Mar 2016 22:06:49 -0700 Subject: [PATCH] syscon: Avoid returning a device on failure If the device cannot be probed, syscon_get_by_driver_data() will still return a useful value in its devp parameter. Ensure that it returns NULL instead.
