From 265697288ec2160ca84707565d6641d46f69b0ff Mon Sep 17 00:00:00 2001 From: Jinjie Ruan ruanjinjie@huawei.com Date: Mon, 19 Aug 2024 20:33:49 +0800 Subject: [PATCH] spi: bcm63xx: Fix missing pm_runtime_disable()
The pm_runtime_disable() is missing in the remove function, fix it by using devm_pm_runtime_enable(), so the pm_runtime_disable() in the probe error path can also be removed.
