Subject: [PATCH] irqchip/s3c24xx: Remove unneeded comparison of unsigned long to 0
Date: Mon, 13 Aug 2018 17:11:44 +0200 [thread overview]
Message-ID: <20180813151144.12407-1-krzk@kernel.org> (raw)
irq_data->hwirq is unsigned long. This fixes GCC warning:
drivers/irqchip/irq-s3c24xx.c: In function 's3c_irqext0_type':
drivers/irqchip/irq-s3c24xx.c:253:19: warning: comparison of unsigned expression >= 0 is always true [-Wtype-limits]
if ((data->hwirq >= 0) && (data->hwirq <= 3)) {
