Subject: [PATCH 4.14 105/164] irqchip/qcom: Fix u32 comparison with value less than zero
Date: Tue, 12 Dec 2017 12:44:45 +0000	[thread overview]
Message-ID: <20171212123448.806421851@linuxfoundation.org> (raw)
In-Reply-To: <20171212123443.785979602@linuxfoundation.org>

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
