[PATCH 2/2] net: fec_ptp: Use platform_get_irq_xxx_optional() to avoid error message

From: Anson Huang
Date: Wed Oct 09 2019 - 06:18:21 EST


Use platform_get_irq_byname_optional() and platform_get_irq_optional()
instead of platform_get_irq_byname() and platform_get_irq() for optional
IRQs to avoid below error message during probe:

[ 0.795803] fec 30be0000.ethernet: IRQ pps not found
[ 0.800787] fec 30be0000.ethernet: IRQ index 3 not found

Fixes: 7723f4c5ecdb ("driver core: platform: Add an error message to platform_get_irq*()")
