    ACPI: don't free non-existent backlight in acpi video module
    
    acpi_video_put_one_device was attempting to remove sysfs entries and
    unregister a backlight device without first checking that said backlight
    device structure had been created.

commit 82e7784f57a81faf673b09bc468e736d582fe754

    toshiba_acpi: return on a fail path
    
    Return from bt_rfkill_poll() when hci_get_radio_state() fails.
    
    value is invalid in that case and should not be assigned to the rfkill
    state.
    
    This also fixes a double unlock bug.

commit b0de22bdffa2e9a8e280d769c59f866605268484
Author: Lin Ming <ming.m.lin@xxxxxxxxx>

    ACPICA: Windows compatibility fix: same buffer/string store
    
    Fix a compatibility issue when the same buffer or string is
    stored to itself. This has been seen in the field. Previously,
    ACPICA would zero out the buffer/string. Now, the operation is
    treated as a NOP.
