However, the early failure path after the first acquire_bus()\ncall uses a bare 'return ret;', which leaks dma_buffer whenever the bus\nacquire fails.\n\nReplace the early return with goto fail so the existing cleanup path\nruns.\n\nFound via a custom Coccinelle semantic patch hunting for kmalloc'd\nlocals leaked on early-return error paths in driver firmware-download\ncode."
