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