Please break lines for commit logs at around 76 chars and mention the
exact compiler warning being fixed.

this warning is already fixed by ca82876 (omap2: fix assorted compiler
warnings).
As this warning is a false positive (i.e. gpio_mux is never used
uninitialized), making the line read
struct omap_mux *uninitialized_var(gpio_mux);
(IMHO) would have been a bit better for both, readabily and (probably)
generated code.
Thanks
