struct sys_reg_desc has 2 function pointers (among others):
reset and .get_user . The functions implementing these are
usually named accordingly. For invariant registers only
reset is used but set to functions that are called get_*
(which is usually used to implement .get_user).

E.g.: invariant_sys_regs[0].reset == get_midr_el1

When trying to figure out this code I was confused by this, hence
this patch..
