From 43cfba56d312f0a45e0b3eaa63606e05ae7fac14 Mon Sep 17 00:00:00 2001 From: Ray Zhang Date: Mon, 10 Oct 2022 04:55:47 +0000 Subject: [PATCH] mtd: mtdoops: change printk() to counterpart pr_ functions To comply with latest kernel code requirement, change printk() to counterpart pr_ functions in mtdoops driver: - change printk(INFO) to pr_info() - change printk(DEBUG) to pr_debug() - change printk(WARNING) to pr_warn() - change printk(ERR) to pr_err() Note that only if dynamic debugging is enabled or DEBUG is defined, printk(KERN_DEBUG) and pr_debug() are equivalent; Otherwise pr_debug() is no-op, causing different behavior.
