Hello there,

[linux-4.13/drivers/gpu/drm/nouveau/nvkm/subdev/therm/fan.c:93]: (warning) Opposite inner 'if' condition leads to a dead code block.

Source code is

if (target != duty) { u16 bump_period = fan->bios.bump_period; u16 slow_down_period = fan->bios.slow_down_period; u64 delay;

if (duty > target) delay = slow_down_period; else if (duty == target) delay = min(bump_period, slow_down_period) ;

Last if can never be true, so call to min can never execute. Suggest code rework.

Regards

David Binderman
