Subject: [PATCH 3.12 012/182] ARM: OMAP4: Fix definition of IS_PM44XX_ERRATUM

From: Nishanth Menon <nm@...com>

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

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

commit 07484ca33ef83900f5cfbde075c1a19e5a237aa1 upstream.

Just like IS_PM34XX_ERRATUM, IS_PM44XX_ERRATUM is valid only if
CONFIG_PM is enabled, else, disabling CONFIG_PM results in build
failure complaining about the following:
arch/arm/mach-omap2/built-in.o: In function `omap4_boot_secondary':
:(.text+0x8a70): undefined reference to `pm44xx_errata'

Fixes: c962184 (ARM: OMAP4: PM: add errata support)
