Please excuse me for sending v2 on the same day, it fixes erorr paths for drmm allocation code. In a lots of places in DPU driver memory is allocated by using the kzalloc and then manually freed using kfree. However thes memory chunks have a well-defined life cycle. They are either a part of the driver's runtime and can be devm_kzalloc'ed or are exposed to userspace via the DRM objects and thus can be drmm_alloc'ed. Implement corresponding runtime resource manangement for the DPU driver. Dependencies: [1]. [1] https://patchwork.freedesktop.org/series/118839/ Changes since v1: - Fix error handling for some of drmm_foo_alloc() functions, which return error pointer in case of an error rather than typical NULL.
