Without the update, we'll only see the new dmesg buffer after the
reboot, but previously we could see it right away. Making an oops
visible in pstore filesystem before reboot is a somewhat dubious
feature, but removing it wasn't an intentional change, so let's
restore it.
For this we have to make persistent_ram_save_old() safe for calling
multiple times, and also extern it.

Also, remove the redundant && ISA/PCI/PCMCIA/USB for the if

GCC complains that we use an uninitialized variable if the user passes
an invalid parameter to adf4350_read(). I decided that we should return
-EINVAL instead in that case.
However, when I looked up at adf4350_write() it returned -ENODEV for
that condition. In the end, I decided the -EINVAL was the right thing
and I change adf4350_write() to match.
