Subject: [PATCH 1/2] net: fec_main: Use platform_get_irq_byname_optional() to avoid error message
Date: Wed,  9 Oct 2019 18:15:47 +0800
Message-ID: <1570616148-11571-1-git-send-email-Anson.Huang@nxp.com> (raw)

Failed to get irq using name is NOT fatal as driver will use index
to get irq instead, use platform_get_irq_byname_optional() instead
of platform_get_irq_byname() to avoid below error message during
probe:

[    0.819312] fec 30be0000.ethernet: IRQ int0 not found
[    0.824433] fec 30be0000.ethernet: IRQ int1 not found
[    0.829539] fec 30be0000.ethernet: IRQ int2 not found

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