Subject: [PATCH AUTOSEL 4.9 07/18] MIPS: uprobes: remove set but not used variable 'epc'
Date: Fri, 14 Jun 2019 16:30:23 -0400 [thread overview]
Message-ID: <20190614203037.27910-7-sashal@kernel.org> (raw)
In-Reply-To: <20190614203037.27910-1-sashal@kernel.org>
From: YueHaibing <yuehaibing@huawei.com>
[ Upstream commit f532beeeff0c0a3586cc15538bc52d249eb19e7c ]
Fixes gcc '-Wunused-but-set-variable' warning:
arch/mips/kernel/uprobes.c: In function 'arch_uprobe_pre_xol':
arch/mips/kernel/uprobes.c:115:17: warning: variable 'epc' set but not used [-Wunused-but-set-variable]
It's never used since introduction in
commit 40e084a506eb ("MIPS: Add uprobes support.")
