Subject: [PATCH] irqchip/qcom: fix u32 comparison with value less than zero
Date: Fri, 17 Nov 2017 18:35:53 +0000 [thread overview]
Message-ID: <20171117183553.2739-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The comparison of u32 nregs being less than zero is never true since
nregs is unsigned. Fix this by making nregs a signed integer.
Fixes: f20cc9b00c7b ("irqchip/qcom: Add IRQ combiner driver")
