Subject: [PTCH] x86: APM: fix build warning when PROC_FS is not enabled
Date: Fri, 14 Sep 2018 15:10:29 -0700
Message-ID: <be39ac12-44c2-4715-247f-4dcc3c525b8b@infradead.org> (raw)

From: Randy Dunlap <rdunlap@infradead.org>

Fix build warning in apm_32.c when CONFIG_PROC_FS is not enabled:

../arch/x86/kernel/apm_32.c:1643:12: warning: 'proc_apm_show' defined but not used [-Wunused-function]
 static int proc_apm_show(struct seq_file *m, void *v)

Fixes: 3f3942aca6da ("proc: introduce proc_create_single{,_data}")
