The patch titled
PCI ACPI: fix uninitialized variable in __pci_osc_support_set
has been removed from the -mm tree. Its filename was
pci-acpi-fix-uninitialized-variable-in-__pci_osc_support_set.patch
This patch was dropped because it was merged into mainline or a subsystem tree
The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/

Subject: PCI ACPI: fix uninitialized variable in __pci_osc_support_set
From: Kenji Kaneshige <kaneshige.kenji@xxxxxxxxxxxxxx>
If the ACPI namespace doesn't have any device object corresponding to the
specified hid, 'retval' in __pci_osc_support_set() is not changed by the
acpi_query_osc() callback. Since 'retval' is not initizlized in the current
implementation, the contents of 'retval' is undefined in this case. This
causes a mis-handling of ctrlset_buf[OSC_SUPPORT_TYPE] and will cause an
unexpected result in the subsequent pci_osc_control_set() call as a result.
