I'd kinda like to keep the const-ness because I can see device drivers
putting static structures in const ( i.e. read-only TEXT ) space and
would like to have the safety factor of knowing that they aren't actually
modified - not just not modified by the initialization routine, but also
not modified later on in the device driver code.
But I also want to eventually quiet the warning -- I agree that for
SYSINIT's, loosing const is not a huge issue. Quieting the warning
without fixing the problem with -Wcast-qual enabled is not pretty, though.
I think -Wcast-qual is pretty important if we intend to fix the volatile
conversion mess.
