Hi Rob
So 0-day shows some people have worked around this with #ifdef
CONFIG_OF around the match table.
I checked the object code for the file i'm interested in. The
optimiser has correctly throw away the match table and all code around
it with the inline stub.
Which do you prefer? This patch and i remove the #ifdef, or the old
stub and if add #ifdef around the driver i'm getting warnings from?
