From 2861ae302f6bf7221db2dac5bd4cf0f2e4cab13b Mon Sep 17 00:00:00 2001 From: Luc Van Oostenryck Date: Fri, 1 Jun 2018 17:21:21 +0200 Subject: riscv: use NULL instead of a plain 0 sbi_remote_sfence_vma() & sbi_remote_fence_i() takes a pointer as first argument but some macros call them with a plain 0 which, while legal C, is frowned upon in the kernel. Change this by replacing the 0 by NULL.
