Hi all, After merging the bluetooth tree, today's linux-next build (powerpc allyesconfig) failed like this: In file included from include/linux/byteorder/big_endian.h:5, from arch/powerpc/include/uapi/asm/byteorder.h:14, from arch/powerpc/include/asm/qspinlock_types.h:6, from arch/powerpc/include/asm/spinlock_types.h:10, from include/linux/spinlock_types_raw.h:7, from include/linux/ratelimit_types.h:7, from include/linux/printk.h:9, from include/asm-generic/bug.h:31, from arch/powerpc/include/asm/bug.h:116, from include/linux/ktime.h:24, from include/linux/poll.h:7, from include/net/bluetooth/bluetooth.h:29, from net/bluetooth/mgmt_config.c:7: net/bluetooth/mgmt_config.c: In function 'read_def_system_config': include/uapi/linux/byteorder/big_endian.h:34:26: error: conversion from 'unsigned int' to 'short unsigned int' changes value from '536870912' to '0' [-Werror=overflow] 34 | #define __cpu_to_le32(x) ((__force __le32)__swab32((x))) | ^ include/linux/byteorder/generic.h:88:21: note: in expansion of macro '__cpu_to_le32' 88 | #define cpu_to_le32 __cpu_to_le32 | ^~~~~~~~~~~~~ net/bluetooth/mgmt_config.c:40:19: note: in expansion of macro 'cpu_to_le32' 40 | { cpu_to_le32(_param_code_), sizeof(__u32) }, \ | ^~~~~~~~~~~ net/bluetooth/mgmt_config.c:127:17: note: in expansion of macro 'TLV_SET_U32' 127 | TLV_SET_U32(0x0020, idle_timeout), | ^~~~~~~~~~~ cc1: all warnings being treated as errors Caused by commit afa20d8099dd ("Bluetooth: mgmt: Add idle_timeout to configurable system parameters") I have reverted that commit for today. -- Cheers, Stephen Rothwell
