The fix involves setting 'err' to '-EINVAL' before each 'goto
out_err_unreserve'.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_queue.c:265 kfd_queue_acquire_buffers()
warn: missing error code 'err'
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_queue.c
226 int kfd_queue_acquire_buffers(struct kfd_process_device *pdd, struct queue_properties *properties)
227 {
228 struct kfd_topology_device *topo_dev;
229 struct amdgpu_vm *vm;
230 u32 total_cwsr_size;
231 int err;
232
233 topo_dev = kfd_topology_device_by_id(pdd->dev->id);
234 if (!topo_dev)
235 return -EINVAL;
236
237 vm = drm_priv_to_vm(pdd->drm_priv);
238 err = amdgpu_bo_reserve(vm->root.bo, false);
239 if (err)
240 return err;
241
242 err = kfd_queue_buffer_get(vm, properties->write_ptr, &properties->wptr_bo, PAGE_SIZE);
243 if (err)
244 goto out_err_unreserve;
245
246 err = kfd_queue_buffer_get(vm, properties->read_ptr, &properties->rptr_bo, PAGE_SIZE);
247 if (err)
248 goto out_err_unreserve;
249
250 err = kfd_queue_buffer_get(vm, (void *)properties->queue_address,
251 &properties->ring_bo, properties->queue_size);
252 if (err)

254
255 /* only compute queue requires EOP buffer and CWSR area */
256 if (properties->type != KFD_QUEUE_TYPE_COMPUTE)

This is clearly a success path.
258
259 /* EOP buffer is not required for all ASICs */

263 properties->eop_buf_bo->tbo.base.size,
264 topo_dev->node_props.eop_buffer_size);
--> 265 goto out_err_unreserve;
This has err in the label name. err = -EINVAL?

err?
279 }
280

err? Not sure.

288 total_cwsr_size = (topo_dev->node_props.cwsr_size + topo_dev->node_props.debug_memory_size)
289 * NUM_XCC(pdd->dev->xcc_mask);
290 total_cwsr_size = ALIGN(total_cwsr_size, PAGE_SIZE);

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
