Hi, This is the result of testing randconfig with KCONFIG_SEED=0xEE7AB52F in next-20240703 vanilla tree on Ubuntu 22.04 LTS. GCC used is gcc (Ubuntu 12.3.0-1ubuntu1~22.04) 12.3.0. The particular warning is as follows: drivers/input/misc/twl4030-pwrbutton.c:33: warning: expecting prototype for twl4030(). Prototype was for PWR_PWRON_IRQ() instead The offending line was brought with the commit 68d8bf0436001. 23 #include <linux/module.h> 24 #include <linux/init.h> 25 #include <linux/kernel.h> 26 #include <linux/errno.h> 27 #include <linux/input.h> 28 #include <linux/interrupt.h> 29 #include <linux/of.h> 30 #include <linux/platform_device.h> 31 #include <linux/mfd/twl.h> 32 33 #define PWR_PWRON_IRQ (1 << 0) 34 This time I really cannot tell what is confusing the compiler (GCC 12.3.0). As we know, warnings might be a sign that something is wrong which I cannot see, but you might. Best regards, Mirsad Todorovac
