roxell · hdeller · commit 39b1e779b6e2 · 2020-12-15T05:41:11.000+01:00
When building tinyconfig on parisc the following warnign shows up:

/tmp/arch/parisc/kernel/pci-dma.c:338:12: warning: 'proc_pcxl_dma_show' defined but not used [-Wunused-function]
 static int proc_pcxl_dma_show(struct seq_file *m, void *v)
            ^~~~~~~~~~~~~~~~~~

Mark the function as __maybe_unused to fix the warning.
