Use comedi_timeout() to wait for the analog input end-of-conversion. Combine the logic for the pcl812 and acl812 end-of-conversion in the helper function to simplify the driver. Signed-off-by:

Use comedi_timeout() to wait for the analog input pipe full, scanning, amd end-of-conversion status. The status to check it passed as the 'context' to comedi_timeout(). Use comedi_timeout() to wait for the analog output end-of-conversion. This also fixes a possible bug where invalid data is returned for the analog input read if the conversion did not complete, The analog output has a similar possible bug where the cached readback value is incorrect if the conversion times out.

The wait_for() macro in this driver is a bit nasty. It effects control flow which according to the CodingStyle is a _very_ bad idea. The mux_busy() and ad_done() macros are also bad since they rely on a local variable having a specific name. Remove these macros and use comedi_timeout() to wait for the analog input mux busy completion and end-of-conversion. Both of these are detected by reading the same register and testing different bits. Pass the bits to test as the 'context' to the callback function. The dt282x_ai_cmd() function also checks for the mux busy completion. The 'insn' is not available here but passing NULL is safe because nothing uses it. Signed-off-by:

Use comedi_timeout() to wait for the analog input end-of-conversion. 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 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:
