[PATCH 1/2] power: bq24190: Remove gratuitous dummy function

From: Thierry Reding
Date: Thu Mar 13 2014 - 04:07:33 EST


From: Thierry Reding <treding@xxxxxxxxxx>

Check for OF support using IS_ENABLED(CONFIG_OF). This will enable the
compiler to eliminate dead code if OF support is disabled. With that in
place, the dummy implementation of bq24190_setup_dt() for non-DT setups
can be removed as the compiler will automatically discard the function
when appropriate.
