Hi!
There is a potential race in drivers/iio/adc/vf610_adc.ko.
Handlers vf610_set_conversion_mode and vf610_write_raw are called via
device_attibute interface, but they are related to different attributes,
so may be executed in parallel. vf610_set_conversion_mode acquires the
mutex indio_dev->mlock, and vf610_write_raw does not. Thus updating the
structure 'info' may be performed simultaneously.
Should vf610_write_raw also acquire the same mutex indio_dev->mlock?
