Subject[PATCH] powerpc/4xx: Fix return value check in hsta_msi_probe()
Date
From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

In case of error, the functions platform_get_resource() and kmalloc()
returns NULL not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
