Hi Linus, After merging the gpio tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_gpio_save_regs': drivers/gpio/gpio-mpc8xxx.c:57:21: error: implicit declaration of function 'in_be32' [-Werror=implicit-function-declaration] mpc8xxx_gc->data = in_be32(mm->regs + GPIO_DAT); ^ drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_gpio_set': drivers/gpio/gpio-mpc8xxx.c:100:2: error: implicit declaration of function 'out_be32' [-Werror=implicit-function-declaration] out_be32(mm->regs + GPIO_DAT, mpc8xxx_gc->data); ^ drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_gpio_dir_in': drivers/gpio/gpio-mpc8xxx.c:139:2: error: implicit declaration of function 'clrbits32' [-Werror=implicit-function-declaration] clrbits32(mm->regs + GPIO_DIR, mpc8xxx_gpio2mask(gpio)); ^ drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_gpio_dir_out': drivers/gpio/gpio-mpc8xxx.c:156:2: error: implicit declaration of function 'setbits32' [-Werror=implicit-function-declaration] setbits32(mm->regs + GPIO_DIR, mpc8xxx_gpio2mask(gpio)); ^ drivers/gpio/gpio-mpc8xxx.c: In function 'mpc512x_irq_set_type': drivers/gpio/gpio-mpc8xxx.c:289:3: error: implicit declaration of function 'clrsetbits_be32' [-Werror=implicit-function-declaration] clrsetbits_be32(reg, 3 << shift, 2 << shift); ^ drivers/gpio/gpio-mpc8xxx.c: In function 'mpc8xxx_probe': drivers/gpio/gpio-mpc8xxx.c:419:26: error: 'NO_IRQ' undeclared (first use in this function) if (mpc8xxx_gc->irqn == NO_IRQ) ^ drivers/gpio/gpio-mpc8xxx.c:419:26: note: each undeclared identifier is reported only once for each function it appears in Exposed by commit 5df7fd46b70b ("pio/qoriq: Add qoriq platforms support") The COMPILE_TEST dependency has revealed several implicit includes ... I have used the gpio tree from next-20160128 for today. -- Cheers, Stephen Rothwell sfr@xxxxxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-next" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
