Add regulator_has_full_constraints() call to poodle board file to let regulator core know that we do not have any additional regulators left. This lets it substitute unprovided regulators with dummy ones. This fixes the following warnings that can be seen on poodle if regulators are enabled: ads7846 spi1.0: unable to get regulator: -517 spi spi1.0: Driver ads7846 requests probe deferral wm8731 0-001b: Failed to get supply 'AVDD': -517 wm8731 0-001b: Failed to request supplies: -517 wm8731 0-001b: ASoC: failed to probe component -517 Cc: stable@xxxxxxxxxxxxxxx Signed-off-by: Dmitry Eremin-Solenikov <dbaryshkov@xxxxxxxxx> --- arch/arm/mach-pxa/poodle.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm/mach-pxa/poodle.c b/arch/arm/mach-pxa/poodle.c index 1319916..e81d216 100644 --- a/arch/arm/mach-pxa/poodle.c +++ b/arch/arm/mach-pxa/poodle.c @@ -25,6 +25,7 @@ #include <linux/gpio.h> #include <linux/i2c.h> #include <linux/i2c/pxa-i2c.h> +#include <linux/regulator/machine.h> #include <linux/spi/spi.h> #include <linux/spi/ads7846.h> #include <linux/spi/pxa2xx_spi.h> @@ -455,6 +456,7 @@ static void __init poodle_init(void) pxa_set_i2c_info(NULL); i2c_register_board_info(0, ARRAY_AND_SIZE(poodle_i2c_devices)); poodle_init_spi(); + regulator_has_full_constraints(); } static void __init fixup_poodle(struct tag *tags, char **cmdline) -- 2.1.3 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
