Hi Mark, After merging the regmap tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpio/gpio-da9052.c:25:35: fatal error: linux/mfd/da9052/gpio.h: No such file or directory So, it looks like this would never have built (include/linux/mfd/da9052/gpio.h never existed) but noone ever enabled CONFIG_PMIC_DA9052 before (which CONFIG_GPIO_DA9052 depends on). drivers/gpio/gpio-da9052.c was added with commit 07bfc9152365 ("GPIO: DA9052 GPIO module v3") in v3.1-rc1. I have added this patch for today: From: Stephen Rothwell Date: Thu, 15 Dec 2011 16:59:59 +1100 Subject: [PATCH] gpio: disable broken driver Signed-off-by: Stephen Rothwell --- drivers/gpio/Kconfig | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/drivers/gpio/Kconfig b/drivers/gpio/Kconfig index 79199f4..e338013 100644 --- a/drivers/gpio/Kconfig +++ b/drivers/gpio/Kconfig @@ -70,7 +70,7 @@ config GPIO_GENERIC config GPIO_DA9052 tristate "Dialog DA9052 GPIO" - depends on PMIC_DA9052 + depends on PMIC_DA9052 && BROKEN help Say yes here to enable the GPIO driver for the DA9052 chip. -- 1.7.7.3 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au http://www.canb.auug.org.au/~sfr/
