Date: Mon, 15 Sep 2014 21:24:23 -0700 From: Martin Kelly <martin@...tingkelly.com> To: x86@...nel.org Cc: vishwesh.m.rudramuni@...el.com, joe@...ches.com, hpa@...ux.intel.com, aubrey.li@...ux.intel.com, linux-kernel@...r.kernel.org, Martin Kelly <martin@...tingkelly.com>, Martin Kelly <martkell@...zon.com> Subject: [PATCH] x86/pmc_atom: Fix warning when CONFIG_DEBUG_FS=n When compiling with CONFIG_DEBUG_FS=n, gcc emits an unused variable warning for pmc_atom.c because "ret" is used only within the CONFIG_DEBUG_FS block. This patch fixes it up to eliminate "ret" when CONFIG_DEBUG_FS=n.
