Subject: [PATCH] ia64: salinfo: placate defined-but-not-used warning
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 0de155752b152d6bcd96b5b5bf20af336abd183a

[ Upstream commit 0de155752b152d6bcd96b5b5bf20af336abd183a ]

When CONFIG_PROC_FS is not set, proc_salinfo_show() is not used.  Mark the
function as __maybe_unused to quieten the warning message.

../arch/ia64/kernel/salinfo.c:584:12: warning: 'proc_salinfo_show' defined but not used [-Wunused-function]
  584 | static int proc_salinfo_show(struct seq_file *m, void *v)
