Minor issue. This way, the mutex is left uninitialized for ADC_TM5_HC 
devices. I'd move the mutex_init() call to the _probe function itself.

Please do not do this. Create a separate adc_tm5_gen2_init function.
Add init() callback to adc_tm5_data structure.

Here you read the data (args.args[0]) before checking that it is 
actually available (args.args_count is not zero). Please correct the 
sequence.
