From: Rafael J. Wysocki Date: Mon, 15 Jul 2019 11:03:28 +0000 (+0200) Subject: ACPICA: Return u32 from acpi_dispatch_gpe() X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=6921de898ba8f2ec91cfea70e7160b89c477382e;p=openwrt%2Fstaging%2Fblogic.git ACPICA: Return u32 from acpi_dispatch_gpe() In some cases it is useful to know whether or not the acpi_ev_detect_gpe() called by acpi_dispatch_gpe() has found the GPE to be active, so return the return value of it (whose data type is u32) from latter.
