Use comedi_timeout() to wait for the analog input and output end-of- conversion. Use break to exit the loop when a timeout occurs during the analog input read so that common code can be used to disable the device. Signed-off-by:

Use comedi_timeout() to wait for the analog input and output end-of- conversions. This prevents a deadlock condition that could occur by providing a timeout in case the end-of-conversion does not happen. Signed-off-by:

Use comedi_timeout() to wait for the analog input end-of-conversion. Since this is the sample skeleton driver, add comments about how the callback function works with comedi_timeout(). Signed-off-by:

Introduce a comedi core helper function to handle the boilerplate needed by the drivers to busy- wait for a condition to occur. Typically this condition is the analog input/output end-of-conversion used with the comedi (*insn_read) and (*insn_write) operations. To use this function, the drivers just need to provide a callback that checks for the desired condition. The callback should return 0 if the condition is met or -EBUSY if it is still waiting. Any other errno will be returned to the caller. If the timeout occurs before the condition is met -ETIMEDOUT will be returned. The parameters to the callback function are the comedi_device, comedi_subdevice, and comedi_insn pointers that were passed to the (*insn_read) or (*insn_write) as well as an unsigned long, driver specific, 'context' that can be used to pass any other information that might be needed in the callback. This 'context' could be anything such as the register offset to read the status or the bits needed to check the status. The comedi_timeout() function itself does not use any of these parameters. This will help remove all the crazy "wait this many loops" used by some of the drivers. It also creates a common errno for comedi to detect when a timeout occurs. ADC/DAC conversion times are typically pretty fast, usually around 100K samples/sec (10 usec). A conservative timeout of 1 second is used in comedi_timeout(). Signed-off-by:
