Include header file internal.h in debugfs.c and change the return value's type in header file internal.h. This eliminates the following warning in debugfs.c: drivers/acpi/debugfs.c:16:13: warning: no previous prototype for ‘acpi_debugfs_init’ [-Wmissing-prototypes] Signed-off-by: Rashika Kheria <rashika.kheria@xxxxxxxxx> Reviewed-by: Josh Triplett <josh@xxxxxxxxxxxxxxxx> --- drivers/acpi/debugfs.c | 3 +++ drivers/acpi/internal.h | 2 +- 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/drivers/acpi/debugfs.c b/drivers/acpi/debugfs.c index b55d6a2..96bcaf7 100644 --- a/drivers/acpi/debugfs.c +++ b/drivers/acpi/debugfs.c @@ -6,6 +6,7 @@ #include <linux/init.h> #include <linux/debugfs.h> #include <acpi/acpi_drivers.h> +#include "internal.h" #define _COMPONENT ACPI_SYSTEM_COMPONENT ACPI_MODULE_NAME("debugfs"); @@ -13,7 +14,9 @@ ACPI_MODULE_NAME("debugfs"); struct dentry *acpi_debugfs_dir; EXPORT_SYMBOL_GPL(acpi_debugfs_dir); +#ifdef CONFIG_DEBUG_FS void __init acpi_debugfs_init(void) { acpi_debugfs_dir = debugfs_create_dir("acpi", NULL); } +#endif diff --git a/drivers/acpi/internal.h b/drivers/acpi/internal.h index 8ef9787..c2e35bd 100644 --- a/drivers/acpi/internal.h +++ b/drivers/acpi/internal.h @@ -63,7 +63,7 @@ void acpi_scan_hotplug_enabled(struct acpi_hotplug_profile *hotplug, bool val); #ifdef CONFIG_DEBUG_FS extern struct dentry *acpi_debugfs_dir; -int acpi_debugfs_init(void); +void acpi_debugfs_init(void); #else static inline void acpi_debugfs_init(void) { return; } #endif -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
