From d5372c39132958679c480d0295dd328c741c7a41 Mon Sep 17 00:00:00 2001 From: Vasily Gorbik Date: Wed, 25 Sep 2019 16:47:36 -0700 Subject: [PATCH] kexec: restore arch_kexec_kernel_image_probe declaration arch_kexec_kernel_image_probe function declaration has been removed by commit 9ec4ecef0af7 ("kexec_file,x86,powerpc: factor out kexec_file_ops functions"). Still this function is overridden by couple of architectures and proper prototype declaration is therefore important, so bring it back. This fixes the following sparse warning on s390: arch/s390/kernel/machine_kexec_file.c:333:5: warning: symbol 'arch_kexec_kernel_image_probe' was not declared. Should it be static?
