--- Comment #9 from spasswolf at web.de ---
get_reg_field_value(value, HPD0_DC_HPD_INT_STATUS, DC_HPD_SENSE)
is just a macro expanding to an inline function, i.e.
current_status = (value & HPD0_DC_HPD_INT_STATUS__DC_HPD_SENSE_MASK) >>
HPD0_DC_HPD_IN_STATUS__DC_HPD_SENSE__SHIFT;
with ..._MASK = 0x2 being 0x2 and ...__SHIFT = 0x1, problems seem to occur when
current_status != 0.
