Please pack them in increasing order and it will be perfect
(i.e. 0xd0, 0xd1, 0xd2, 0xd3 instead of current 0xd0, 0xd2 (?), 0xd3, 0xd1).

Minor nit: please insert spaces (as in similar declarations).

            ^^ Missing "b".

The "if (RTL_R8(0xef) & 0x08)" and "if (RTL_R8(0xef) & 0x010)" conditionals
from the previous iteration have been removed. If it is done on purpose, a
short explanation or notification in the description of the patch is always
welcome.
