From 1cb7b1e0de6a1f8f071f4a146e3d10f3a662f707 Mon Sep 17 00:00:00 2001 From: Thomas Renninger Date: Thu, 31 Mar 2011 13:36:38 +0200 Subject: ACPI EC: remove dead code static void acpi_ec_gpe_query(void *ec_cxt); -> The function is right above this declaration -> not needed. poll_force is also not used, cleaned up in ec.c and its users: compal-laptop and msi-laptop.

The previous test used the dmi_name_in_vendors function which searches a number of DMI fields, while the new test checked only the BIOS vendor, which is known to not match on an ASUS F5GL laptop which requires ECDT validation. Add a rule to ec_dmi_table based on an alternative DMI pattern for ASUS hardware as found elsewhere in the kernel.
