All of these strings bloat the kernel image. Can we just return ret
instead and if something goes wrong we can use a debug patch to figure
out which register write failed? Would a register write even fail to
begin with?
Will remove wherever possible.

Any reason we can't use dev_err() here?
It's interrupt handler. Here dev variable is not available.
So we shall remove print as per your previous comment or keep as it is.
