The ADC stabilization delays in compensation mode and battery sensing mode do not require atomic context. Using mdelay() here results in unnecessary busy waiting. Replace mdelay(1) with fsleep(1000) to allow the scheduler to run other tasks while waiting for the ADC to stabilize. Also fix a minor typo in the comment ("adc" -> "ADC").quoted
Suggested-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com>I haven't suggested the idea, I only suggested to use fsleep() for the purpose.
