编译make zImage时后报错:
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]
修改:
进入ezx-pcap.c,到第205行:
将} while (gpio_get_value(irq_to_gpio(pcap->spi->irq)));改为} while (gpio_get_value(pdata->gpio));
并找ezx-pcap.h,在struct pcap_platform_data加上int gpio;
