Subject: ACPI: glue: Change return type of two functions to void
X-Git-Tag: accepted/tizen/unified/20230118.172025~6537^2~2^3~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7d625e5b143d07f26c437ede6b18730c2fc4d1b5;p=platform%2Fkernel%2Flinux-rpi.git

ACPI: glue: Change return type of two functions to void

Since the return values of acpi_device_notify() and
acpi_device_notify_remove() are discarded by their only caller,
change their return type to void.

No functional impact.
