From 7afb095df3e3c2f0d2f27d2d27bbe574ca9479f0 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 10 Nov 2025 19:54:35 +0100 Subject: [PATCH] s390/syscalls: Add pt_regs parameter to SYSCALL_DEFINE0() syscall wrapper All system call wrappers should match the sys_call_ptr_t type. This is not the case for system calls without parameters. Add the missing pt_regs parameter there too. Note: this is currently not a problem, since the parameter is unused. However it prevents to create a correctly typed system call table in C. With the current assembler implementation this works because of missing type checking.
