From: Austin Kim <austin.kim@xxxxxxx>
The local variable 'i' is used to be incremented inside while loop
within sidtab_convert_tree(). Before while loop, 'i' is set to 0
inside if/else statement.
Since there is no 'goto' statement within sidtab_convert_tree(),
it had better initialize 'i' as 0 once before if/else statement.
