From: Rafael J. Wysocki Date: Wed, 30 Apr 2014 20:36:33 +0000 (+0200) Subject: PNP / ACPI: Do not return errors if _DIS or _SRS are not present X-Git-Tag: omap-for-v3.16/pm-signed~16^2~1^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a8d22396302b7e4e5f0a594c1c1594388c29edaf;p=pandora-kernel.git PNP / ACPI: Do not return errors if _DIS or _SRS are not present The ACPI PNP subsystem returns errors from pnpacpi_set_resources() and pnpacpi_disable_resources() if the _SRS or _DIS methods are not present, respectively, but it should not do that, because those methods are optional. For this reason, modify pnpacpi_set_resources() and pnpacpi_disable_resources(), respectively, to ignore missing _SRS or _DIS. This problem has been uncovered by commit 202317a573b2 (ACPI / scan: Add acpi_device objects for all device nodes in the namespace) and manifested itself by causing serial port suspend to fail on some systems.
