Thanks Tom. Patch is Reviewed-By: Rex Zhu <Rex.Zhu at amd.com> Best Regards Rex -----Original Message----- From: amd-gfx [mailto:amd-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of Tom St Denis Sent: Tuesday, September 05, 2017 8:03 PM To: amd-gfx at lists.freedesktop.org Cc: StDenis, Tom Subject: [PATCH] drm/amd/powerplay: Fix psm_set_user_performance_state() We now pass a pointer to a pointer which seems to be what they meant in the first place. The previous version was modifying a pointer passed by value.
