Subject: irqchip/qcom: Fix u32 comparison with value less than zero

From: Colin Ian King <colin.king@canonical.com>


[ Upstream commit e9990d70e8a063a7b894c5cbb99f630a0f41200d ]

The comparison of u32 nregs being less than zero is never true since
nregs is unsigned. Fix this by making nregs a signed integer.
