Add new API nvgpu_get_gpu_instance_id_from_cdev() that returns GPU instance id from nvgpu_cdev pointer. Store cdev pointer in channel private data channel_priv and ctrl node private data gk20a_ctrl_priv. Update below functions to pass cdev pointer : __gk20a_channel_open() gk20a_channel_open_ioctl() In gk20a_channel_ioctl(), extract gpu instance id using cdev pointer stored in channel_priv and new API nvgpu_get_gpu_instance_id_from_cdev(). Extract GR instance id using nvgpu_grmgr_get_gr_instance_id() Invoke context creation API inside nvgpu_gr_exec_with_err_for_instance() so that context is created with correct GR instance id.
