It's caused by the absence of "{ }" in syscon_rk3399.c
,which will lead to memory overflow like below.According
to Sysmap file ,we can find the function buck_get_value
of rk808 is just follow the compatible struct,the pointer
"of_match" point to "buck_get_value",but it is not a
struct and don't have member of compatible, In this case,
system crash. So,on the face, it looks like that rk808 is
guilty.but he is really innocent.
while (of_match->compatible) { <<----------
if (!strcmp(of_match->compatible, compat)) {
*of_idp = of_match;
return 0;
}
of_match++;
}
