From b2fe288eac7247f83b52377b4134ecc5cd856bf2 Mon Sep 17 00:00:00 2001 From: Vincent Cuissard Date: Tue, 3 Nov 2015 19:19:34 +0100 Subject: NFC: nfcmrvl: free reset gpio Reset GPIO shall be freed by the driver since the device used in devm_ calls can be still valid on unregister. If user removes the module and inserts it again, the devm_gpio_request will fail because the underlying physical device (e.g i2c) was not removed so the device management won't have freed the gpio.
