nouveau_fence_emit() can fail before and after initializing the dma-fence and hence before and after initializing the dma-fence' kref. In order to avoid nouveau_fence_emit() potentially failing before dma-fence initialization pass the channel to nouveau_fence_new() already and perform the required check before even allocating the fence. While at it, restore the original behavior of nouveau_fence_new() and add nouveau_fence_create() for separate (pre-)allocation instead. Always splitting up allocation end emit wasn't a good idea in the first place. Hence, limit it to the places where we actually need to pre-allocate.

`strncpy` is deprecated for use on NUL-terminated destination strings [1]. A suitable replacement is `strscpy` [2] due to the fact that it guarantees NUL-termination on its destination buffer argument which is _not_ the case for `strncpy`! Also remove extraneous if-statement as it can never be entered. The return value from `strncpy` is it's first argument. In this case, `...dyndbg_cmd` is an array: | char dyndbg_cmd[VPU_DYNDBG_CMD_MAX_LEN]; ^^^^^^^^^^ This can never be NULL which means `strncpy`'s return value cannot be NULL here. Just use `strscpy` which is more robust and results in simpler and less ambiguous code. Moreover, remove needless `... - 1` as `strscpy`'s implementation ensures NUL-termination and we do not need to carefully dance around ending boundaries with a "- 1" anymore.

Currently, NO_PREFETCH is passed implicitly through drm_nouveau_gem_pushbuf_push::length and drm_nouveau_exec_push::va_len. Since this is a direct representation of how the HW is programmed it isn't really future proof for a uAPI. Hence, fix this up for the new uAPI and split up the va_len field of struct drm_nouveau_exec_push, such that we keep 32bit for va_len and 32bit for flags. For drm_nouveau_gem_pushbuf_push::length at least provide NOUVEAU_GEM_PUSHBUF_NO_PREFETCH to indicate the bit shift. While at it, fix up nv50_dma_push() as well, such that the caller doesn't need to encode the NO_PREFETCH flag into the length parameter. Signed-off-by:

If a sched job depends on a dma-fence from a job from the same GPU scheduler instance, but a different scheduler entity, the GPU scheduler does only wait for the particular job to be scheduled, rather than for the job to fully complete. This is due to the GPU scheduler assuming that there is a scheduler instance per ring. However, the current implementation, in order to avoid arbitrary amounts of kthreads, has a single scheduler instance while scheduler entities represent rings. As a workaround, set the DRM_SCHED_FENCE_DONT_PIPELINE for all out-fences in order to force the scheduler to wait for full job completion for dependent jobs from different entities and same scheduler instance. There is some work in progress [1] to address the issues of firmware schedulers; once it is in-tree the scheduler topology in Nouveau should be re-worked accordingly.

This panel has been implemented in commit eae74888 ("drm/panel-simple: Add Innolux G156HCE-L01 panel entry") with a higher clock than the typical one mentioned on the documentation to avoid flickering on the unit tested. Testing on a different unit shows that the panel actually works with the intended 70.93 MHz clock and even lower frequencies so the flickering is likely caused either by a defective unit or by other different components such as the bridge.

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert the mediatek drm drivers from always returning zero in the remove callback to the void returning variant. Reviewed-by:
