staging: comedi: pcl812: introduce pcl812_ai_clear_eoc()

Browse source

Introduce a helper function to clear the end-of-conversion flag.

This flag is set when an analog input conversion is finished and the
hardware generates an interrupt request. Writing any value to the
register resets the flag and re-enables the interrupt.

Remove a redundant call in pcl812_ai_cancel().
