[Asaf Vertz]

Fixed the following warnings (reported by cppcheck):
[drivers/staging/iio/light/tsl2x7x_core.c:1150]: (warning) %d in format string (no. 1)
requires 'int' but the argument type is 'unsigned int'.
[drivers/staging/iio/light/tsl2x7x_core.c:1150]: (warning) %d in format string (no. 2)
requires 'int' but the argument type is 'unsigned int'.
[drivers/staging/iio/light/tsl2x7x_core.c:1150]: (warning) %d in format string (no. 3)
requires 'int' but the argument type is 'unsigned int'.
