Comment # 68 on bug 73338 from Chernovsky Oleg

(In reply to Martin Peres from comment #66)

Martin, there're things I think I didn't get correctly:
- What should I return if pwm1_enable is 0 and I'm trying to push 50 into pwm1?
- Can pwm1_enabled value be 2 after I push 0 to it? Radeon default fan value
comes from fuse and it's not 100%
