I've researched the change to PLL_SERIAL_2, and this is correct. I think
your change to REG_ENABLE_SPACE is also correct. This looks like a bug
fix to me, so maybe consider having it applied to previous kernel
versions as well?

Also... please try putting yourself in the position of a reviewer of your
own patches - read the patch and then read the description, and ask whether
the description is adequate for the patch... the description talks just
about the ENABLE_SPACE register. But what about the PLL_SERIAL_2 register
changes? They're *totally* not described.
