Hi everybody, I tried to use the LM75 (temperature sensor) driver with a Philips LM75A. The LM75 driver tries to identify the chip using a heuristic based on non-implemented registers: - The LM75 ignores the 5 high address bits, register i is can thus be read at i+n*8 (0 <= i <= 7; n < 32). This is true for the LM75A as well. - Reading unimplemented registers 0x04-0x07 from the LM75 returns the last read value. The LM75A returns 0xff. Here is a patch (against 2.6.17-rc6) which modifies the unused addresses test to accept 0xff as valid values.
