Subject: [PATCH] MIPS: OCTEON: fix unreachable code in octeon_irq_init_ciu
Date:   Mon, 11 Jan 2021 03:36:05 -0800
Message-Id: <20210111113605.3863-1-dong.menglong@zte.com.cn>
Precedence: bulk

From: Menglong Dong <dong.menglong@zte.com.cn>

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.
