Subject: [PATCH AUTOSEL 3.18 15/26] KVM: x86: fix empty-body warnings
Date: Wed,  5 Dec 2018 04:54:19 -0500	[thread overview]
Message-ID: <20181205095430.8019-15-sashal@kernel.org> (raw)
In-Reply-To: <20181205095430.8019-1-sashal@kernel.org>

From: Yi Wang <wang.yi59@zte.com.cn>

[ Upstream commit 354cb410d87314e2eda344feea84809e4261570a ]

We get the following warnings about empty statements when building
with 'W=1':

arch/x86/kvm/lapic.c:632:53: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
arch/x86/kvm/lapic.c:1907:42: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
arch/x86/kvm/lapic.c:1936:65: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]
arch/x86/kvm/lapic.c:1975:44: warning: suggest braces around empty body in an ‘if’ statement [-Wempty-body]

Rework the debug helper macro to get rid of these warnings.
