From 832b371097eb928d077c827b8f117bf5b99d35c0 Mon Sep 17 00:00:00 2001 From: Lukas Wunner Date: Mon, 15 Jan 2024 16:05:26 +0100 Subject: gpiolib: Fix scope-based gpio_device refcounting Commit 9e4555d1e54a ("gpiolib: add support for scope-based management to gpio_device") sought to add scope-based gpio_device refcounting, but erroneously forgot a negation of IS_ERR_OR_NULL(). As a result, gpio_device_put() is not called if the gpio_device pointer is valid (meaning the ref is leaked), but only called if the pointer is NULL or an ERR_PTR(). While at it drop a superfluous trailing semicolon.
