Title
spi: amlogic: spifc-a4: Fix DMA mapping error handling
Summary
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.

Unnecessary goto: When the first DMA mapping (sfc-\u003edaddr) fails,\n   nothing needs cleanup. Use direct return instead of goto.\n2. Double-unmap bug: When info DMA mapping failed, the code would\n   unmap sfc-\u003edaddr inline, then fall through to out_map_data which\n   would unmap it again, causing a double-unmap.\n3. Wrong unmap size: The out_map_info label used datalen instead of\n   infolen when unmapping sfc-\u003eiaddr, which could lead to incorrect\n   DMA sync behavior."
