That should have been in the changelog!

When fixing warnings or compilations errors, the compiler output should
also be in the changelog.

I don't recall seeing such warnings and I cannot make them happen with
drivers/gpio/gpiolib.c or with drivers/gpio/max732x.c or with
drivers/gpio/pca953x.c.  So we still don't know what this patch
does :(

Well sure it's small.  But converting things to `const' carries a
fairly high risk of adding new warnings or breaking the build.
