Subject: [PATCH] regulator: core: Use postcore_initcall(regulator_init_complete)
Date: Mon, 25 Nov 2013 19:57:35 -0200 [thread overview]
Message-ID: <1385416655-7859-1-git-send-email-festevam@gmail.com> (raw)
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.
