hum. How did it get into a non-working state?

From the logs, it looks like it was working OK for Andrea Paterniani
when he patched it in April last year.

Ordinarily I'd be asking whether this replacement of one driver with
another is a 100% seamless change. But I guess that the audience for
SPI drivers are sufficiently technical to be able to handle the odd
Kconfig changes, module parameter changes, module name changes, etc.

But I do think that if there are any such user-visible changes, they
should be described in the changelog. And I think there are such
changes - the module name at least?


Is it possible and desirable to retain both drivers for a while? Would
that ease the transition? It also gives people a fallback driver to
use, if your new driver doesn't work for them. Just like eepro100.c,
which lived for five years ;)


But it's really hard to make any decisions about this because the
changelog failed to provide any details about the "non working state".
