From 7b490a8ab0f2d3ab8d838a4ff22ae86edafd34a1 Mon Sep 17 00:00:00 2001 From: Menglong Dong Date: Mon, 11 Jan 2021 05:27:25 -0800 Subject: MIPS: OCTEON: fix unreachable code in octeon_irq_init_ciu The type of 'r' in octeon_irq_init_ciu is 'unsigned int', so 'r < 0' can't be true. Fix this by change the type of 'r' and 'i' from 'unsigned int' to 'int'. As 'i' won't be negative, this change works.
