Subject: [PATCH v2 01/12] NFC: pn544: Switch to devm_acpi_dev_add_driver_gpios()
Date: Mon, 5 Jun 2017 23:19:58 +0300 [thread overview]
Message-ID: <20170605202009.78561-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20170605202009.78561-1-andriy.shevchenko@linux.intel.com>
Switch to use managed variant of acpi_dev_add_driver_gpios() to simplify
error path and fix potentially wrong assingment if ->probe() fails.
