requires 'int' but the argument type is 'unsigned int'.
[drivers/staging/iio/impedance-analyzer/ad5933.c:367]: (warning) %d in format string (no. 1)
requires 'int' but the argument type is 'unsigned int'.
[drivers/staging/iio/impedance-analyzer/ad5933.c:367]: (warning) %d in format string (no. 2)
requires 'int' but the argument type is 'unsigned int'.
[drivers/staging/iio/impedance-analyzer/ad5933.c:367]: (warning) %d in format string (no. 3)
requires 'int' but the argument type is 'unsigned int'.
[drivers/staging/iio/impedance-analyzer/ad5933.c:367]: (warning) %d in format string (no. 4)
