    Subject[PATCH AUTOSEL 4.14 34/67] fbdev/via: fix defined but not used warning
    Date
    From: Randy Dunlap <rdunlap@infradead.org>

    [ Upstream commit b6566b47a67e07fdca44cf51abb14e2fbe17d3eb ]

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

    ../drivers/video/fbdev/via/viafbdev.c:1471:12: warning: 'viafb_sup_odev_proc_show' defined but not used [-Wunused-function]
