William Breathitt Gray 9fa82f031a iio: addac: stx104: Fix race condition when converting analog-to-digital ... [ Upstream commit 4f9b80aefb ] The ADC conversion procedure requires several device I/O operations performed in a particular sequence. If stx104_read_raw() is called concurrently, the ADC conversion procedure could be clobbered. Prevent such a race condition by utilizing a mutex.
