Fix W=1 warnings:

cs42l42.c: In function 'cs42l42_handle_device_data':
cs42l42.c:1661:12: warning: comparison of unsigned expression >= 0 is
always true [-Wtype-limits]

      |            ^~
cs42l42.c:1679:12: warning: comparison of unsigned expression >= 0 is
always true [-Wtype-limits]

cs42l42.c:1698:23: warning: comparison of unsigned expression >= 0 is
