Subject: [PATCH 27/27] NFC: nxp-nci: Fix probing without ACPI

From: Stephan Gerhold <[email-masked]>
Date: Mon, 9 Dec 2019 19:53:43 +0100

[ Upstream commit 868afbaca1e2a7923e48b5e8c07be34660525db5 ]

devm_acpi_dev_add_driver_gpios() returns -ENXIO if CONFIG_ACPI
is disabled (e.g. on device tree platforms).
In this case, nxp-nci will silently fail to probe.

The other NFC drivers only log a debug message if
devm_acpi_dev_add_driver_gpios() fails.
Do the same in nxp-nci to fix this problem.
