Hans de Goede 4039254acb surface: surface3_power: Fix battery readings on batteries without a serial number ... commit 21d90aaee8 upstream. The battery on the 2nd hand Surface 3 which I recently bought appears to not have a serial number programmed in. This results in any I2C reads from the registers containing the serial number failing with an I2C NACK. This was causing mshw0011_bix() to fail causing the battery readings to not work at all. Ignore EREMOTEIO (I2C NACK) errors when retrieving the serial number and continue with an empty serial number to fix this.
