The actual constification of the attribute will happen with a central
change to the CONFIGFS_ATTR* macros. But all users of the macro
will need to be prepared to handle the constness.

I have a branch with the full conversion here:

https://git.kernel.org/pub/scm/linux/kernel/git/thomas.weissschuh/linux.git/log/?h=b4/configfs-const

 73 files changed, 241 insertions(+), 248 deletions(-)

 Most driver changes are really trivial. But a few do more interesting
 things. My goal is to heavily reduce the amount of patches in this
 branch by merging patches to the same subsystem.

 The last four patches will be the finalization going again through
 the configfs tree.
