I have the following Smatch report.
drivers/pwm/pwm-cadence-ttc.c:73 cadence_ttc_pwm_set_invert() error:
buffer overflow 'priv->invert' 2 <= 2
drivers/pwm/pwm-cadence-ttc.c:138 cadence_ttc_pwm_set_config() error:
buffer overflow 'priv->invert' 2 <= 2
Indeed yes, the code allows a maximum index of 2 into an array with 2
elements, so that is out of bounds. My question is which is wrong?
Should the array have 3 elements or should the index be limited to 1, or
is the value being checked 1 based?
Thanks,
Andrew
