Subject[PATCH AUTOSEL for 4.14 007/110] phy: cpcap-usb: Fix platform_get_irq_byname's error checking.
Date
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.

Fixes: 6d6ce40f63af ("phy: cpcap-usb: Add CPCAP PMIC USB support")
