Hm, I just had a look at all ->read/write_reg() call sites and it seems
we have the same problem in other places. Maybe it's just better to fix
the problem in m25p80 ->read/write_reg() implems for now

Do you plan to send a new fix doing that, or should I? I'd really like
to have the fix queued to mtd/master early this week, so that it
spends a bit of time in -next.

I guess better if you could as I haven't started anything yet. I'm not so familiar with the code to see what would be best way to fix, reverting m25p80_read_reg/m25p80_write_reg back to spi_write(), the whole commit or do some kmemdup() there.
