Oh way better, thanks.
It also saved a lot of line when priting:
static void psr2_su_blocks_sprintf(struct seq_file *m,
struct drm_i915_private *dev_priv)
{
unsigned i;
for (i = 0; i < 8; i++) {
u32 val = I915_READ(EDP_PSR2_SU_STATUS(i));
val = val >>
EDP_PSR2_SU_STATUS_NUM_SU_BLOCKS_FRAME_SHIFT(i);
val &= EDP_PSR2_SU_STATUS_NUM_SU_BLOCKS_MASK;
seq_printf(m, "\tSU blocks in frame N-%d: %d\n", i,
val);
}
}
