The only usage of these is to pass their address to
sysfs_{create,remove}_group(), which takes pointers to const struct
attribute_group. Make them const to allow the compiler to put them in
read-only memory.

I checked the file. Indeed, those structs are only used in
sysfs_{create,remove}_group. So I agree that they can be constified.

They also pass all the automated tests:
