From 3863360c15da47e18d894268ad6182fdc7caf0c7 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 11 Oct 2017 13:16:43 +0200 Subject: [PATCH] media: vimc: Fix return value check in vimc_add_subdevs() In case of error, the function platform_device_register_data() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
