[POWERPC] UPIO_TSI cleanup
(le32_to_cpu(x) >> 8) & 0xff is a very odd way to spell (x >> 16) & 0xff, even if that code is hit only on ppc. The value is host-endian - we've got it from readl(), after all... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Paul Mackerras <paulus@samba.org>
