to set the dev->regs I use the value read from revision register.

to read the revision register I do a get_sync first. This in turn leads
to the call to resume handler.
At this point the regs is NULL and so the check.

After reading the register and checking the scheme bit.
the reg map is populated.

How can this issue be solved?
