Date: Mon, 25 Nov 2013 19:57:35 -0200 From: Fabio Estevam <festevam@...il.com> To: broonie@...nel.org Cc: shawn.guo@...aro.org, linux-kernel@...r.kernel.org, thierry.reding@...il.com, Fabio Estevam <fabio.estevam@...escale.com> Subject: [PATCH] regulator: core: Use postcore_initcall(regulator_init_complete) From: Fabio Estevam <fabio.estevam@...escale.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.
