The adt7475_update_device() function returns error pointers. The
problem is that in show_pwmfreq() we dereference it before the check.
And then in pwm_use_point2_pwm_at_crit_show() there isn't a check at
all. I don't know if it's required, but it silences a static checker
warning and it's doesn't hurt anything to check.
