[PATCH 4/9] eeepc-laptop: pull out ACPI_STORE_FUNC and ACPI_SHOW_FUNC macros

From: Frans Klaver
Date: Wed Sep 17 2014 - 17:48:59 EST


Pull out macros EEEPC_ACPI_STORE_FUNC and EEEPC_ACPI_SHOW_FUNC. These
macros define functions that call store_sys_acpi() and show_sys_acpi()
respectively. This helps prevent duplication later on.
