From: Fabio Estevam <fabio.estevam@freescale.com>
Commit 22ceeee1 (pwm-backlight: Add power supply support) introduced the usage of regulator API into the pwm backlight driver and caused a regression on some boards like mx28evk and mx6qsabresd, resulting in blank display output:
pwm-backlight backlight.18: dummy supplies not allowed
Calling regulator_init_complete via late_initcall can be too 'late' for the regulator to be available for the pwm backlight driver.
Call regulator_init_complete with postcore_initcall level instead.
