Subject: [PATCH 5.11 473/775] sparc: fix led.c driver when PROC_FS is not enabled

From: Randy Dunlap <rdunlap@...radead.org>

[ Upstream commit b3554aa2470b5db1222c31e08ec9c29ab33eabc7 ]

Fix Sparc build when CONFIG_PROC_FS is not enabled.

Fixes this build error:
arch/sparc/kernel/led.c:107:30: error: 'led_proc_ops' defined but not used [-Werror=unused-const-variable=]
     107 | static const struct proc_ops led_proc_ops = {
         |                              ^~~~~~~~~~~~
   cc1: all warnings being treated as errors

Fixes: 97a32539b956 ("proc: convert everything to "struct proc_ops"")
