Subject: [PATCH] drm/amd/display: Fix harmless type mismatch in allocation
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While converting to kmalloc_obj() API, a type assignment mismatch was
found between the desired struct dcn42_resource_pool and the allocated
struct dcn401_resource_pool. Fix the type (it is harmless: the objects
have the same contents and size).
