In the kfd_process_device_init_vm function, a valid error code is now
returned when the associated Process Address Space ID (PASID) is not
present.
If the address space virtual memory (avm) does not have an associated
PASID, the function sets the ret variable to -EINVAL before proceeding
to the error handling section. This ensures that the calling function,
such as kfd_ioctl_acquire_vm, can appropriately handle the error,
thereby preventing any issues during virtual memory initialization.
Fixes the below:
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c:1694 kfd_process_device_init_vm()
warn: missing error code 'ret'
drivers/gpu/drm/amd/amdgpu/../amdkfd/kfd_process.c
1647 int kfd_process_device_init_vm(struct kfd_process_device *pdd,
1648 struct file *drm_file)
1649 {
...
1690
1691 if (unlikely(!avm->pasid)) {
1692 dev_warn(pdd->dev->adev->dev, "WARN: vm %p has no pasid associated",
1693 avm);
--> 1694 goto err_get_pasid;
ret = -EINVAL?
1695 }
Fixes:

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.
