From 04aaca197f16aff608e19ee98b1e55f535d746be Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 17 Jun 2020 17:33:13 +0900 Subject: char: raw: do not leak CONFIG_MAX_RAW_DEVS to userspace include/uapi/linux/raw.h leaks CONFIG_MAX_RAW_DEVS to userspace. Userspace programs cannot use MAX_RAW_MINORS since CONFIG_MAX_RAW_DEVS is not available anyway. Remove the MAX_RAW_MINORS definition from the exported header, and use CONFIG_MAX_RAW_DEVS in drivers/char/raw.c While I was here, I converted printk(KERN_WARNING ...) to pr_warn(...) and stretched the warning message.
