Pan Bian 81b039ec36 iio: adc: cpcap: fix incorrect validation 
Function platform_get_irq_byname() returns a negative error code on
failure, and a zero or positive number on success. However, in function
cpcap_adc_probe(), positive IRQ numbers are also taken as error cases.
Use "if (ddata->irq < 0)" instead of "if (!ddata->irq)" to validate the
return value of platform_get_irq_byname().
