From 7cd68b364f833fdf1438e5d2c591bd650bb89bdc Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 3 Dec 2023 16:24:05 +0100 Subject: [PATCH] hwmon: (nzxt-kraken2) Fix error handling path in kraken2_probe() [ Upstream commit 35fe2ad259a3bfca15ab78c8ffb5278cb6149c89 ] There is no point in calling hid_hw_stop() if hid_hw_start() has failed. There is no point in calling hid_hw_close() if hid_hw_open() has failed. Update the error handling path accordingly.
