Comment (by CodeforEvolution):

 I think I see the reason for this: the driver hasn’t been updated to be
 “SMAP safe” (As in the driver does not use special methods like
 “user_memcpy” to protect the kernel from userspace). I would take a look
 at this, but I have unfortunately been very busy lately.
