[POWERPC] Fix return value check logic in debugfs virq_mapping setup
debugfs_create_file() returns a non-NULL (non-zero) value in case of success, not a NULL value. This fixes this non-critical boot-time debugging error message: [ 1.316386] calling irq_debugfs_init+0x0/0x50 [ 1.316399] initcall irq_debugfs_init+0x0/0x50 returned -12 after 0 msecs [ 1.316411] initcall irq_debugfs_init+0x0/0x50 returned with error code -12 Signed-off-by: Emil Medve <Emilian.Medve@Freescale.com> Acked-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
