Subject: arch/arm/mach-omap2/i2c.c:130:2: error: implicit declaration of function 'omap_pm_set_max_mpu_wakeup_lat'

Hi Linus, Wolfram,
FYI, kernel build failed on

All error/warnings:
arch/arm/mach-omap2/i2c.c: In function 'omap_pm_set_max_mpu_wakeup_lat_compat':
arch/arm/mach-omap2/i2c.c:130:2: error: implicit declaration of function 'omap_pm_set_max_mpu_wakeup_lat' [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
The root cause is, i2c.c (which is always compiled in arch/arm/mach-omap2/Makefile)
uses omap_pm_set_max_mpu_wakeup_lat() which is defined in omap-pm-noop.c (which
is compiled only on CONFIG_OMAP_PM_NOOP).
