hwmon: (f75375s) pwmX_mode sysfs files writable for f75375 variant
Fix value check in set_pwm_mode(). Instead of checking for chip variant there, make pwmX_mode sysfs nodes only writable on f75375 variant. Signed-off-by: Riku Voipio <riku.voipio@movial.fi> Acked-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
