[PATCH AUTOSEL 4.9 6/9] platform/x86: intel-hid: Fix return value check in check_acpi_dev()

[Sasha Levin]

From: Lu Wei <luwei32@xxxxxxxxxx>

[ Upstream commit 71fbe886ce6dd0be17f20aded9c63fe58edd2806 ]

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: ecc83e52b28c ("intel-hid: new hid event driver for hotkeys")
