From: Tom Rix <trix@xxxxxxxxxx> Clang static analysis reports this issue mt6360-adc.c:277:20: warning: Assigned value is garbage or undefined data.values[i++] = val; ^ ~~~ val is set by a successful call to m6360_adc_read_channel(). A negative return is checked but within m6360_adc_read_channel, a non zero check is done. Strengthen the check to non zero.
