nouveau_abi16_ioctl_channel_alloc() and nouveau_cli_init() simply call their corresponding *_fini() counterpart. This can lead to nouveau_sched_fini() being called without struct nouveau_sched ever being initialized in the first place. Instead of embedding struct nouveau_sched into struct nouveau_cli and struct nouveau_chan_abi16, allocate struct nouveau_sched separately, such that we can check for the corresponding pointer to be NULL in...

...he issues of firmware schedulers; once it is in-tree the scheduler topology in Nouveau should be re-worked accordingly.

Looks like I spoke too soon, I just hit the problem with the drm-next tree. I'm able to repro the problem by hav...
