From: Randy Dunlap <rdun...@infradead.org>
Fix build warnings in drivers/isdn/capi/ when CONFIG_PROC_FS is not
enabled by marking the unused functions as __maybe_unused.
../drivers/isdn/capi/capi.c:1324:12: warning: 'capi20_proc_show' defined but
not used [-Wunused-function]
../drivers/isdn/capi/capi.c:1347:12: warning: 'capi20ncci_proc_show' defined
but not used [-Wunused-function]
../drivers/isdn/capi/capidrv.c:2454:12: warning: 'capidrv_proc_show' defined
but not used [-Wunused-function]
