This v4 series addresses memory handling issues in the FastRPC driver's Audio PD remote heap. Patch 1 is a clear, correct bugfix. Patch 2 is a reasonable race-condition fix. Patch 4 is a clean, standard cleanup. However, **Patch 3 has critical bugs** that will cause kernel crashes at module removal time: the `remote_heap` allocated via `kzalloc` in probe has `NULL` `dev` and `fl` fields, so calling `fastrpc_buf_free()` on it dereferences NULL pointers. There are also resource leak issues and use of potentially uninitialized data. The series should not be merged until Patch 3 is reworked.
