From 3d9c1d39237eb0495616447a82a312ee957d60f8 Mon Sep 17 00:00:00 2001 From: Gleb Fotengauer-Malinovskiy Date: Fri, 6 May 2022 17:24:54 +0000 Subject: [PATCH] rfkill: uapi: fix RFKILL_IOCTL_MAX_SIZE ioctl request definition commit a36e07dfe6ee71e209383ea9288cd8d1617e14f9 upstream. The definition of RFKILL_IOCTL_MAX_SIZE introduced by commit 54f586a91532 ("rfkill: make new event layout opt-in") is unusable since it is based on RFKILL_IOC_EXT_SIZE which has not been defined. Fix that by replacing the undefined constant with the constant which is intended to be used in this definition.
