From 9fab10cdf58099beff08d74f6b4a6633305c5754 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 7 Jul 2010 08:21:48 +0800 Subject: panasonic-laptop: fix acpi_pcc_write_sset return value In current implementation, acpi_pcc_write_sset return 1 if write is successful, 0 if write is failed. But all the callers consider acpi_pcc_write_sset return 0 if write is successful and return negtive if write is failed. This patch changes the implementation of acpi_pcc_write_sset to return 0 if write is successful, -EIO if write is failed.
