Subject: [PATCH 3.12 24/64] drm: radeon: ni_dpm: Fix unused variable warning when CONFIG_ACPI=n

From: Fabio Estevam <fabio.estevam@...escale.com>

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

===============

commit 71473dbd66d4a61be4cd531ef96b4877f6ee3941 upstream.

With CONFIG_ACPI=n the following build warning is seen:

drivers/gpu/drm/radeon/ni_dpm.c:3448:31: warning: unused variable 'eg_pi' [-Wunused-variable]

Move the definition of eg_pi inside the CONFIG_ACPI 'if' block.
