[PATCH] block/DAC960.c: fix defined but not used build warnings

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

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]
