* drm/amdgpu: don't try to recreate sysfs entries on resumeAlex Deucher2015-10-231-0/+5
| | | | | | | | Fixes an error on resume caused by: fa022a9b65d2886486a022fd66b20c823cd76ad9 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
* drm/amdgpu/dpm: don't add pwm attributes if DPM is disabledAlex Deucher2015-10-191-2/+6
| | | | | | | | | PWM fan control is only available with DPM. There is no non-DPM support on amdgpu, so we should never get a crash here because the sysfs nodes would never be created in the first place. Add the check just in case to be on the safe side.

* drm/amdgpu: don't grab dev->struct_mutex in pm functionsDaniel Vetter2015-08-171-2/+0
| | | | | | | | | | | | | | Similar to radeon, except that amdgpu doesn't even use struct_mutex to protect anything like the shared z buffer (sane gpu architecture, yay!). And the code already grabs the globa adev->ring_lock, so this code can't race with itself. Which makes struct_mutex completely redundnant. Remove it.
