Subject: phy: cpcap-usb: Fix platform_get_irq_byname's error checking.

From: Arvind Yadav <arvind.yadav.cs@gmail.com>


[ Upstream commit e796cc6a3a9186c92092e2f5929cf8f65b56cf01 ]

The platform_get_irq_byname() function returns negative if an error occurs.
zero or positive number on success. platform_get_irq_byname() error
checking for zero is not correct.
