From: Pan Bian bianpan2016@163.com
commit 81b039ec36a41a5451e1e36f05bb055eceab1dc8 upstream.
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().
