The surrounding code had wandered to another function, so it's suprising
it applied at all. Here's respin.

"rm -rf" only sounds scary if you don't have backups

Subject: [PATCH] hwmon (f75375s) fix buggy if() properly
Fix value check in set_pwm_mode(). Instead of checking for
chip variant there, make pwmX_mode sysfs nodes only writable
on f75375 variant.
