Now that the driver core can properly handle constant struct bus_type,
move the s3c6410_subsys variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.

This "Now" was confusing last time and is still... There is often no
"Now" in multi-tree-repo-approach. If the patch allows it went through
different tree, this is still false. If this was already merged into
mainline, just say since which commit or which release.

I raised my concerns last time, so please fix all your future patches
after receiving such feedback.



Best regards,
Krzysztof

You're right, I'll keep this in mind. Will send a v2.
