From 28ea54bade76e2d47cb8cdb96e427cfb90d3eea7 Mon Sep 17 00:00:00 2001 From: Palmer Dabbelt Date: Tue, 7 Nov 2023 07:55:29 -0800 Subject: RISC-V: Don't rely on positional structure initialization Without this I get a bunch of warnings along the lines of arch/riscv/kernel/module.c:535:26: error: positional initialization of field in 'struct' declared with 'designated_init' attribute [-Werror=designated-init] 535 | [R_RISCV_32] = { apply_r_riscv_32_rela }, This just mades the member initializers explicit instead of positional. I also aligned some of the table, but mostly just to make the batch editing go faster.
