From d3e13ff3c1aa2403d9a5f371baac088daeb8f56d Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 7 Jul 2015 00:31:47 +0200 Subject: ACPI / LPSS: Fix up acpi_lpss_create_device() Fix a return value (which should be a negative error code) and a memory leak (the list allocated by acpi_dev_get_resources() needs to be freed on ioremap() errors too) in acpi_lpss_create_device() introduced by commit 4483d59e29fe 'ACPI / LPSS: check the result of ioremap()'.
