These might read better as
len /= 4;
Where did the magic value of 4 come from?
for (i = 0; i< len; i++) {
u16 devid = be32_to_cpu(*paddr++);
u16 reg = be32_to_cpu(*paddr++);
u16 mask = be32_to_cpu(*paddr++);
u16 val_bits = be32_to_cpu(*paddr++);
Is the main problem that they didn't align, or that the index was
explicit instead of implicit?
