Subject: ACPI / LPSS: Fix up acpi_lpss_create_device()

From: "Rafael J. Wysocki" <[email protected]>

commit d3e13ff3c1aa2403d9a5f371baac088daeb8f56d upstream.

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()'.
