Hi Ronald,

This allows errors during registration to properly fail the probe
function.

Doing this requires waiting for a response from the device inside the
probe function. While this generally takes about 15ms, in case of errors
it could be arbitrarily long, and hence a 3 second timeout is used.

This also adds 3 second timeouts to the drain functions to avoid the
potential for suspend or remove hanging forever.

Question: is it possible to read command response synchronously as well?
I.e. I was wondering if we could add 2 (or 1?) more read xfers for the
actual result that is coming after the status response, and then we
could use spi_sync() to send the command and read the whole thing.

Thanks.
