Subject: platform/x86: mlx-platform: Fix copy-paste error in mlxplat_init()
Patch-mainline: v4.19-rc1
Git-commit: 207da7128a6d61a1ce3d052b3dfb10d237af6078
References: bsc#1112374

The return value from platform_device_register_resndata() is not checked
correctly. The test is done against a wrong variable. This patch fix it.
