Subject[PATCH 4.18 084/235] platform/x86: toshiba_acpi: Fix defined but not used build warnings
Date
4.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit c2e2a618eb7104e18fdcf739d4d911563812a81c ]

Fix a build warning in toshiba_acpi.c when CONFIG_PROC_FS is not enabled
by marking the unused function as __maybe_unused.

../drivers/platform/x86/toshiba_acpi.c:1685:12: warning: 'version_proc_show' defined but not used [-Wunused-function]
