Revision a7654211d0ffeaa8eb0545ea00f8445242cbce05 authored by Tang Bin on 20 May 2020, 09:55:32 UTC, committed by David S. Miller on 22 May 2020, 00:26:54 UTC 
net: sgi: ioc3-eth: Fix return value check in ioc3eth_probe()
 
In the function devm_platform_ioremap_resource(), if get resource
failed, the return value is ERR_PTR() not NULL. Thus it must be
replaced by IS_ERR(), or else it may result in crashes if a critical
error path is encountered.
