From 11b345ab79a1986fd9da365f646621d9ced9dcfb Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Tue, 6 Jun 2017 13:59:26 +0800 Subject: [PATCH] irqchip/sunxi-nmi: Const-ify sunxi_sc_nmi_reg_offs structures The sunxi_sc_nmi_reg_offs, which hold the register offsets for the various variants, is never modified, and only used at init time within the init functions referenced by IRQCHIP_DECLARE, which themselves are tagged __init. Const-ify the sunxi_sc_nmi_reg_offs structures, and tag them as __initconst.
