dmaengine: xilinx: xdma: Workaround truncation compilation error
Increase length to be copied to be large enough to overcome the following compilation error. The buf is large enough for this purpose. drivers/dma/xilinx/xilinx_dpdma.c: In function ‘xilinx_dpdma_debugfs_desc_done_irq_read’: drivers/dma/xilinx/xilinx_dpdma.c:313:39: error: ‘snprintf’ output may be truncated before the last format character [-Werror=format-truncation=] 313 | snprintf(buf, out_str_len, "%d", | ^ drivers/dma/xilinx/xilinx_dpdma.c:313:9: note: ‘snprintf’ output between 2 and 6 bytes into a destination of size 5 313 | snprintf(buf, out_str_len, "%d", | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 314 | dpdma_debugfs.xilinx_dpdma_irq_done_count); | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Signed-off-by: Vinod Koul <vkoul@kernel.org> Link: https://lore.kernel.org/r/20231222094017.731917-1-vkoul@kernel.org Signed-off-by: Vinod Koul <vkoul@kernel.org>
