Hi Linus, After merging the gpio tree, today's linux-next build (x86_64 allmodconfig) failed like this: drivers/gpio/gpio-pcf857x.c: In function 'pcf857x_irq_domain_map': drivers/gpio/gpio-pcf857x.c:206:2: error: implicit declaration of function 'set_irq_flags' [-Werror=implicit-function-declaration] set_irq_flags(virq, IRQF_VALID); ^ drivers/gpio/gpio-pcf857x.c:206:22: error: 'IRQF_VALID' undeclared (first use in this function) set_irq_flags(virq, IRQF_VALID); ^ Caused by commit 21fd3cd1874a ("gpio: pcf857x: call the gpio user handler iff gpio_to_irq is done"). set_irq_flags() only exists on arm (and arm64). I have used the gpio tree from next-20130917 for today. -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
