- check return value of nvgpu_mutex_init in clk_mclk.c - declare new callback g->ops.pmu.mclk_deinit() to deinitialize mclk mutexes - and define this callback for gp106 - add corresponding nvgpu_mutex_destroy calls in deinitialization Jira NVGPU-13 Change-Id: I1491c084d330ac9756c9520477e6fe494560e651 Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1321294 Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
