## Description

In the Linux kernel, the following vulnerability has been resolved:  spi: amlogic: spifc-a4: Fix DMA mapping error handling  Fix three bugs in aml_sfc_dma_buffer_setup() error paths: 1. Unnecessary goto: When the first DMA mapping (sfc->daddr) fails,    nothing needs cleanup. Use direct return instead of goto. 2. Double-unmap bug: When info DMA mapping failed, the code would    unmap sfc->daddr inline, then fall through to out_map_data which    would unmap it again, causing a double-unmap. 3. Wrong unmap size: The out_map_info label used datalen instead of    infolen when unmapping sfc->iaddr, which could lead to incorrect    DMA sync behavior.
