It takes a task state as its last argument. We enforce that this state is TASK_UNINTERRUPTIBLE for the time being because other states are not interpreted.
Change usleep_range() to call usleep_range_state() with the state set to TASK_UNINTERRUPTIBLE, which is what Linux does too. The amdgpu DRM driver starte to use usleep_range_state() in Linux 6.13.
This is part of the update of DRM drivers to Linux 6.13.
