powerpc/4xx: Fix return value check in hsta_msi_probe()
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. Signed-off-by: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
