[ Upstream commit 64dd4a5a7d214a07e3d9f40227ec30ac8ba8796e ]
In the function check_acpi_dev(), if it fails to create
platform device, the return value is ERR_PTR() or NULL.
Thus it must use IS_ERR_OR_NULL() to check return value.
Fixes: 332e081225fc ("intel-vbtn: new driver for Intel Virtual Button")
