If anyone has any objections, please let me know. ------------------ From: Arnd Bergmann commit 59ee93a528b94ef4e81a08db252b0326feff171f upstream. The irq_to_gpio function was removed from the pxa platform in linux-3.2, and this driver has been broken since. There is actually no in-tree user of this driver that adds this platform device, but the driver can and does get enabled on some platforms. Without this patch, building ezx_defconfig results in: drivers/mfd/ezx-pcap.c: In function 'pcap_isr_work': drivers/mfd/ezx-pcap.c:205:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann Acked-by: Haojian Zhuang Cc: Samuel Ortiz Cc: Daniel Ribeiro Signed-off-by: Greg Kroah-Hartman --- drivers/mfd/ezx-pcap.c | 2 +- include/linux/mfd/ezx-pcap.h | 1 + 2 files changed, 2 insertions(+), 1 deletion(-) --- a/drivers/mfd/ezx-pcap.c +++ b/drivers/mfd/ezx-pcap.c @@ -202,7 +202,7 @@ static void pcap_isr_work(struct work_st } local_irq_enable(); ezx_pcap_write(pcap, PCAP_REG_MSR, pcap->msr); - } while (gpio_get_value(irq_to_gpio(pcap->spi->irq))); + } while (gpio_get_value(pdata->gpio)); } static void pcap_irq_handler(unsigned int irq, struct irq_desc *desc) --- a/include/linux/mfd/ezx-pcap.h +++ b/include/linux/mfd/ezx-pcap.h @@ -16,6 +16,7 @@ struct pcap_subdev { struct pcap_platform_data { unsigned int irq_base; unsigned int config; + int gpio; void (*init) (void *); /* board specific init */ int num_subdevs; struct pcap_subdev *subdevs;
