    Subject[PATCH AUTOSEL 4.18 85/92] block/DAC960.c: fix defined but not used build warnings
    Date
    From: Randy Dunlap <rdunlap@infradead.org>

    [ Upstream commit 3993e501bf853cce85c5114a704b86b8f486790c ]

    Fix build warnings in DAC960.c when CONFIG_PROC_FS is not enabled
    by marking the unused functions as __maybe_unused.

    ../drivers/block/DAC960.c:6429:12: warning: 'dac960_proc_show' defined but not used [-Wunused-function]
    ../drivers/block/DAC960.c:6449:12: warning: 'dac960_initial_status_proc_show' defined but not used [-Wunused-function]
    ../drivers/block/DAC960.c:6456:12: warning: 'dac960_current_status_proc_show' defined but not used [-Wunused-function]
