iio:adc:berlin2-adc: use short operator format (609e9d88) · Commits · 戴 / test

Use augmented assignment to subtract the offset for negative temperature values. Specify the amount of private data to be allocated through devm_iio_device_alloc() with sizeof(*priv), as it is shorter and common practice in IIO. Signed-off-by:
