Subject: [PATCH AUTOSEL 4.4 02/14] xen/pciback: remove set but not used variable 'old_state'
Date: Tue,  6 Aug 2019 17:37:36 -0400	[thread overview]
Message-ID: <20190806213749.20689-2-sashal@kernel.org> (raw)
In-Reply-To: <20190806213749.20689-1-sashal@kernel.org>

From: YueHaibing <yuehaibing@huawei.com>

[ Upstream commit 09e088a4903bd0dd911b4f1732b250130cdaffed ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/xen/xen-pciback/conf_space_capability.c: In function pm_ctrl_write:
drivers/xen/xen-pciback/conf_space_capability.c:119:25: warning:
 variable old_state set but not used [-Wunused-but-set-variable]

It is never used so can be removed.
